Instead of worst-case scenarios, let’s look at which states are almost certainly below the 1.0 threshold. Most importantly: this is a work in progress. In an interview with The Telegraph in May, Systrom said: “The funny thing about tech is all of us founders are 20 or early-30-somethings, and, OK, we’re growing older, but nobody knows what they are doing when they are 20 or 30-something. In this case, restrictions should continue. It’s interesting to me how many of these organizations intuitively made the right call at just the right time. With every step in time, some susceptible people become infected, some infected people recover to be resistant, and resistant people stay resistant. The last conclusion, and one that I will revisit again in upcoming posts, is that it’s a mistake to analyze a country as a whole. Kevin Systrom’s net worth estimate is $1.5 billion. I’m open to feedback and hope that smarter people out there will both build off of this work as well as help improve it. If R0 is greater than one, the epidemic spreads quickly **. One million were using it three months in. Had I known it was going to be the first photo on Instagram I would have tried a bit harder.”. You can also interpret these numbers in a different way. It’s important to remember that this is a model that shows what happens if we stay the course. However, we can’t rely on any one day too much in trying to guess Rt, as daily case counts are imperfect due to changing testing capacity, lags in data reporting, and random chance. However, using Bayes’ Theorem, we can take the new information we get from each day’s case count to adjust our expectation of what Rt is, getting closer to the true value as more daily data becomes available. Alarmists, however, insisted exponential curves they drew fit the data nightmarishly well. North Dakota’s interval is so wide that it includes many possible values above 1.0—therefore we can’t safely conclude that Rt is truly below 1.0. In New York politicians are resisting these measures, while San Francisco implemented them quickly. Now, two weeks later, Italy’s cases have ballooned to 64,000. I’m hopeful that these predictions push policymakers, local governments and individuals to take extraordinary precautions to reduce transmission rates. I assume beta shrinks by a factor of δ (delta) at each step. Sure enough, the characteristic S-curve emerges. By the way, these lines don’t bend easily. With increasing (more social distancing), we reduce total cases and the rate of new infection. For this, I decided to use pymc3, a library for probabilistic programming. Kevin and his then-girlfriend, Nicole, came over for supper after a … Compare Massachusetts’s new cases per day to Louisiana’s. Inside the Life of The $400 Million Co-Founder of Instagram, Get regular updates from our talented staff on the latest and greatest in the Asian American community, Bhutan’s Parliament Approves Bill to Legalize Gay Sex, 20,000 Chinese American WWII Veterans Awarded With Congressional Gold Medal, Asian American Incomes See Highest Growth Over Last 15 Years, Jocelyn Yow, 25, Makes History as California’s Youngest Mayor of Color, Meet EASTERN PEOPLE, a New Clothing Collective for Asian Cultures, How a Singaporean Woman Built a $1.8 Million Apparel Brand by 24, Hello Kitty’s 92-Year-Old Founder to Pass the Business to His Grandson, Woman Gets Fired After Replying to Boss With an Emoji, Woman Gets New Mercedes, 10-Year VIP Treatment and Trip to Germany After Viral Protest. First, the ‘most likely value’ of Rt for each day, represented by the dots (the more red a dot is, the higher and more dangerous the value of Rt is). Sometimes early isn’t early enough. How quickly would it grow? Random House Business; £20. Whatever they’re doing is working. At the same time, New York Gov. I will analyze specific countries, like Italy, where people are looking to see the effects of a national lockdown. By the first month, Instagram racked up 1 million users. However, let’s assume there’s an equally sized group of individuals that are infectious but asymptomatic roaming out there. Once you look at this chart, you can’t unsee New York’s line. The relationship between the number of cases yesterday and the number of cases today give us a hint of what Rt might be. These states should be aware that their high Rt will lead to exponential growth in cases. I don’t have all the answers, nor do I claim to know the future for certain. Rt is a measure of direction, not absolute size. 7.8m Followers, 534 Following, 1,515 Posts - See Instagram photos and videos from Kevin Systrom (@kevin) Systrom explained the moment he thought of developing Instagram from Burbn while on vacation in Mexico with Schuetz: “I was on vacation with my fiancée – at the time, my girlfriend – Nicole in Mexico when we had the aha moment. But even in these states—the most “under control” in the nation— Rt is still far from the comfortable value of ~0.5. No one knows what the future of COVID-19 holds, but a model can provide a picture of probable outcomes. Some people inhale the virus, and with some probability, become infected themselves. We were walking along the beach and I said that we needed something to help us [the company] stand out. And stories from the time show that there was little enforcement: “There was no immediate disruption to air travel, either, with scheduled flights still departing and landing in Milan. Systrom was also a Googler for two years working as an associate marketing manager for Gmail, Google Calendar and Google Docs. In fact, if we plot the same data, but sort by the high end of the HDI (worst-case scenario) we see this: Now it’s clear that all non-lockdown states cluster on the right-hand side. He is an American by birth and has American ethnicity. We’re left to wonder if we are equipped with the right metrics to guide our path forward. Bettencourt & Ribeiro’s original algorithm to estimate Rt is a function of how many new cases appear each day. Here in California, we’re finishing our first week of shelter in place. The graphs above show two important things. It was a mutual admiration of this place that helped lay the groundwork for my friendship with Kevin Systrom, the cofounder of Instagram, and his wife, Nicole. Note that for simplicity, I’ve assumed a constant population size and that in the terrible case that someone dies, they are counted in the resistant population as they cannot spread the virus. What does this mean? In the days following the Starbucks announcement, the chance of a store having all customers be coronavirus-free went from nearly 100% down to 10%. On March 1st, you could walk freely. If that’s the case, how dangerous is it for us to cross paths? ** Note: In a previous version of this post I wrote that R0 > 1 meant that the virus spread to everyone in the population. Fortunately, there are many ways to this. Instead of considering every previous day of data we have to estimate Rt, I only use the last seven days. What’s the largest group you could be in? Kevin is the son of Douglas Systrom (father) and Diane Systrom (mother). Just two weeks later the picture was far more dire. Louisiana still has far more new cases than Washington per day, but Louisiana’s outbreak will not be growing as nearly quickly as Washington and will soon see cases decline even more rapidly. He was drawn to Stanford when he was interviewing at many different universities, and wanted to study and learn where “people worked hard” while living in a beautiful place. From MySpace and Friendster back in the dark ages to Twitter and YouTube to Facebook and Instagram, today there are more options than ever to keep up with your friends, family, and favorite celebrities. The process then repeats itself with those new users. Not everything went well. Doing so will save countless lives. The more data we get and the more consistent that data is, the more confident we can be in our conclusions. Doing so is mathematically sound and produces more accurate results when the model is compared to actual data, but I admit is not reviewed by anyone. Through my research, I found a model called the SIR model that applies to infectious diseases. The average scenario of the model implies 1.5 million dead in the US – bested by the now widely cited Imperial College study at 2.2 million deaths. This may not be perfect, and if we were very concerned we could try different values. For instance, the model claims there is a 95% chance we will have more than 15.4 million infections in the United States. Mark was like a mentor to Kevin. Kevin Systromstarted his educational career at Middlesex School in Concord, Massachusetts where his love for computer programming was ignited; he, later on, moved to the Standford University where he bagged a degree in Management science and engineering in 2006. Today, there are over 300 million people that use Instagram. At some point though, enough people have recovered that the chances of a susceptible and infected person meeting disappears. In this case, the model claims that 95% of the possible true values lie in the gray band, that is, in the HDI. I also hope that by seeing how bad this can get, we might collectively avoid the worst predicted outcomes by acting quickly and decisively. Imagine an app with 100 users. The line between states and countries starts to blur. In any case, our goal should be to reduce R0 to as small a value as possible. Maine looks to have reduced Rt below 1.0, but the gray band shows us that we cannot safely conclude we are below the safety threshold, since it’s possible that Rt is still above 1.0. At Stanford University, he was a member of the Sigma Nu fraternity- a social organization whose mission is to develop ethical leaders, to foster personal gro… I wanted to try two things. I assume, then, that the average infectious period is about 9 days (5 plus half of 8). In July of 2012, Facebook acquired Instagram for $1 billion in cash and stocks. Credit: Douglas Friedman/Architectural Digest / CNN As you might expect from the co-founder of Instagram, every inch of Kevin Systrom's Lake Tahoe house would look perfectly at home on an influencer's feed. I hope by sharing this work with you, you will consider Rt as the metric that can guide our analysis and decision-making. The change was simple. This is a fancy way of saying: what portion of infected people become healthy and resistant again per unit of time? As I argued in my previous post, when this happens, we need to lock down, so why not lock down now before cases grow? Source of Wealth: Entrepreneur: Net Worth 2020: $1.5 billion: Earnings in 2020: Pending: Yearly Salary: Under Review: House(s) He lives in Holliston, New York, USA: Cars: There are no vehicles shown to the public: All net worths are calculated by applying a proprietary algorithm. If =0.1, infections peak on day 13 but stay under the critical limit of 10 beds. The key is to choose the former before being dealt the latter. After all, California has 40 million residents – Italy has 60M. At the age each of those reached 1,000, New York was sitting in the hundreds. low end of HDI) is above 1.0, indicating the true value of Rt is almost certainly above 1.0. The SIR model attempts to explain both of these situations. It's estimated that Kevin Systrom's net worth is approximately $1.4billion. It uses Bayesian statistics to estimate the most likely value of Rt and also return a credible interval for the true value of Rt. At a party, he pitched the prototype to Baseline Ventures and Andreessen Horowitz who became interested. Instagram, in its own way, was a black swan. The best estimates of IFR (infection fatality ratio), are around 2%. Models like this help us understand if and how our medical system can be overwhelmed depending on specific policy actions that influence . One particular method Bettencourt & Ribeiro described in their 2008 paper, “Real Time Bayesian Estimation of the Epidemic Potential of Emerging Infectious Diseases.” This solution caught my attention because it focuses on the same principles from my first post, Predicting Coronavirus Cases. Safe and legal are two different things. Systrom didn’t respond to a request for comment. If you ran the university and your margin of comfort was 90% of not having any students with COVID-19, you moved classes online at precisely the right time. Invisible droplets, replete with virus, float towards susceptible people. The answer is 78,800 cases. Because the value changes so rapidly, Epidemiologists have argued that the only true way to combat COVID19 is to understand and manage by Rt. When forecasting, you don’t always need a complicated model. At the same time, there are some cases that might happen but are less likely. In the real world, should decrease over time as people become more aware of the virus and people avoid gatherings, work, etc. Surprisingly, Louisiana seems to have turned the corner decisively, even with one of the worst outbreaks. Days later, with cases just topping 1000, California ordered residents statewide to shelter in place. By the time I left a year ago, over a billion users used it every month. Now, you might point out that North Dakota looks well below 1.0 and does not have a lockdown. AD100 Designer Ken Fulk fashions a fabulous Lake Tahoe getaway for Instagram cofounder Kevin Systrom and his wife, Nicole. So here we are. The last section described four knowns: S, I, R, N. We also have three unknowns: (gamma, rate of recovery), (beta, rate of transmission) and (delta, social distancing factor) that we need to estimate. I have to assume shrinks over time because people are smart and distance themselves as they learn about the virus. Let’s call the beginning the day a region (country, state or city) reaches 100 cases. Therefore, I assume = 1/9. Instagram co-founder Kevin Systrom holds fast to the original premises of Silicon Valley: Technology can improve our lives, connecting people helps humanity, and tech guys aren’t just in it for the money. People need to shop for food. Some US states have had a succession of increasingly restrictive lockdowns. I think this is one of the most important dynamics to understand. O N A BEACHSIDE walk in Mexico in 2010, Kevin Systrom’s girlfriend explained the problem with his new photo-sharing app, then called “Codename”. If we don’t act at all, infections peak at 45 so we’re short by 35 beds on day 15. Total cases start slow, ramp exponentially, then linearly and finally taper off at some limit. By then, cases in New York had reached 8,402. Systrom made $400 million in the deal and still remains Instagram’s CEO today. In fact, the graph compresses so quickly, it’s easiest to see in log scale: An interesting overlay is what New York University (NYU) decided to do with their classes. However, this produces a single ‘best guess’ value for and . If you were conservative and wanted to be 99% sure, you’d be below the blue line. The good news is that for the second straight day the number of new cases in Italy has dropped. As the infected group grows, you’re more likely to run into someone sick and catch it yourself. The explicit HDI helps make sure we’re not misled by the data and prematurely conclude something that might be a grave error. Let’s turn to Italy. That being said, the model has tracked the last week very closely, and I’d personally rather have a model than no model at all. What are Kevin Systrom and Mike Krieger's net worth? Instagram was launched in 2010. This is the second key lesson. This is useful when it comes to policy decisions: wait until the high end of gray band is well below 1.0 before resuming normal activity. At the same time, I worry the hesitation–if only for a few days–in New York might be one of the largest public policy mistakes of our generation. If you flip the equation around and solve for group k, you can ask how many cases there has to be in NYC for people to have a 90% chance of knowing one person in their network who has it. Each state and each hot spot in the US will be its own curve because the seeds came in at different times. In almost every case, the conclusions are more dire than people currently believe. This is why it’s important to act quickly with social distancing: the safe group went from 100,000s to 100s in a few days. There’s one metric, however, that has the most promise. Some of those people will be unlucky. Pymc3 allows you to set up a model with knowns and unknowns. In his middle school he entered the world of programming and never took his foot off it. Although only two in every 1000 people have coronavirus in NYC, probability works in such a way that your chances of encountering at least one person in 250 are staggering. I agree, and I’d go further: we not only need to know Rt, we need to know local Rt. Some states like California have been locked down for weeks, while others like Iowa and Nebraska continue to balk at taking action as cases rise. But here it’s important to consider North Dakota’s HDI. But the lesson, if any, from Wuhan is that the most effective action is to lock down when infections are low. I’ve kept most of the math and theory in the notebook, but I’d highly suggest diving in if you’re so inclined. In the case of COVID-19, it seems that the incubation period lasts about 5 days. Maine has fewer cases than the previous examples, so the margins are wider. © NextShark INC. 2018. Since infections start at different times, it’s hard to say which infection is ‘worst’. They often met each other at various gatherings at Stanford when Kevin Systrom was a student there, and after Instagram’s launch, Mark also used to hold Dinner sessions with him at his house. Systrom interned at Odeo, the company that gave birth to Twitter. That filter was X-Pro II, which still exists today, in its original form, in the app. ... Instagram is a discussion of photo and video sharing, executed by Kevin Systrom and Mike Krieger. To do this, you need to define the beginning of a local infection and you need to record total cases over time. While I invite feedback, I’m sharing these results with that disclaimer well in advance. Italy had nearly ten times the number of cases when China took similar action. When you hear ‘flatten the curve’, this is what they’re talking about. Any suggestion that we loosen restrictions when Rt > 1.0 is an explicit decision to let the virus proliferate. Second, these equations are helpful, but they shouldn’t be interpreted too precisely, so stay safe. The equations govern the change in each group per unit of time: S, I, and R are the totals of each group. While at Stanford, Systrom was accepted as one of 12 students to participate in the prestigious Mayfield Fellows Program where future entrepreneurs thoroughly study the tech industry and get hooked up with internships at tech startups. It’s Easter. As an investor over the past year, I started asking myself the same question of other companies as well. Today,…, Hello Kitty founder Shintaro Tsuji is passing the torch to his 31-year-old grandson Tomokuni Tsuji as he steps…, A staff member at a bar in southern China was fired from her job after replying to her…, The woman who conducted a “shameful” protest after exhausting negotiations with a Mercedes-Benz dealership in northwestern China over a…. This is best answered through an example using real data. Our behavior changes, whether mandated or self-prescribed, and that changes the effective R value at any point in time. In this image, I’ve taken the most recent values for Rt and plotted them along with the highest-density interval (HDI) bands (as of the evening of 4/11). New cases slow, infected people recover, and you end up with most people being resistant. Recent tallies imply a 4% IFR, though this is disputed because mild cases go undiagnosed. Italy’s national carrier, Alitalia, said it would reduce the number of flights in and out of Milan.”. As you might expect from the co-founder of Instagram, every inch of Kevin Systrom's Lake Tahoe house would look perfectly at home on an influencer's feed. He said he enjoyed doing many different things as he was growing up. During the same time, Kevin was invited to the tony conference run by an investment bank called Allen & Co. in Arizona. Cases grow exponentially. Although you have a small chance of interacting with someone positive, there are many people taking that chance every day. Any talk of reopening the economy soon will ensure this line stays straight, up, and to the right. He now documents his adventures in food, nature and fashion all around the world and is typically accompanied by his long-time girlfriend and now-fiancée, Nicole Schuetz. The beauty of modeling is that you can decide to adjust this number based on your own beliefs if you disagree. The prognosis is complicated, and I plan to write about that separately. The estimates will change and credible intervals will tighten with new data and we’ll get a clearer picture of what the future holds. If you are infectious for 5 days, is 1/5 because 1/5 of infected people recover every day. First, let’s answer an easier question: in the course of your daily interactions, what are the chances that any one person you interact with has Covid-19? I try my best to explain what it all means. House Judiciary Committee Facebook eventually got its way just two months after … Which states have the epidemic least “under control?” To answer this, I plotted states where the best case (eg. Text messages between Kevin Systrom [me] and Matt Cohler [name redacted]. New York is currently hugging the ‘doubles every two days’ line – which for a state of of nearly 20 million people should give you pause. The newly developed Burbn pivoted to become Instagram. Comparing Maine to the previous states is instructive. In a typical year, the flu kills just 40,000. Somehow, the algorithm wasn’t reflecting the reality that Rt could be < 1.0 as well. They tell their friends, and with any luck they’d stick around for the process to continue with their friends. The other variables are: There’s an issue with , however. If they evolve in predictable ways, ask yourself: why is this time is any different? Kevin Stankiewicz @kevin_stank Key Points Instagram co-founder Kevin Systrom said Monday the coronavirus tracking website he helped build is showing concerning levels of spread in many states. It’s called Rt – the effective reproduction number. Kevin Systrom grew up in a small town called Holliston, just outside of Boston, Massachusetts. When talking about his time in high school, where he attended the small but prestigious boarding school Middlesex in Massachusetts, Systrom explained: “I probably had a rougher experience because I was super-tall and nerdy and into programming, so I was by no means the cool kid … I think that’s why our company works. Besides working well theoretically, this modified version of SIR describes what we’re seeing in the real world, too. And I think that’s a deadly combination in entrepreneurship.”, “The one thing we’ve yet to crack is what’s happening in the world, live. You can review each state in the main graphic at the top, but a denser view might be helpful, too. It’s defined as the number of secondary infections produced by a single infection. In the short run, the model is confident. An estimated 300 thousand people left before the lockdown took place. Each of these curves started with a ‘seed’ individual at a specific time. A sign at Milan’s Linate airport assured passengers that regular service was continuing. So far, it’s unclear how much we’ll change though. At the current rate, NYC will cross this threshold in the next few days. Realizing they were behind, Italy expanded this quarantine to the entire nation the following day, stopping all commercial activity, and finally closing all non-essential businesses on the 21st when the latest case count showed a towering 53,578 cases. But one month out, the credible interval expands dramatically – we cannot be that confident in the future This does not mean we cannot draw conclusions, though. Note that while this post focuses on the high level concepts, those who want to dig in further can find the details in this Jupyter notebook. What follows is an application of Bettencourt & Ribeiro’s process (with an important modification) to US State COVID19 data. Knowing the local Rt allows us to manage the pandemic effectively. He co‑founded Instagram, the world's largest photo sharing website, along with Mike Krieger. Remember that is the number of people an infected person infects over time. Ashton Kutcher was once reportedly saved by Instagram founder Kevin Systrom after a ski house they were staying at went up in flames. It might start with a sneeze. And as always, you can get in touch by email or reaching out on Twitter or Instagram @kevin. While R0 is a useful measure, it is flawed in an important way: it’s static. It means historians are going to be able to look back at humanity at this point in time and engage, and understand what has happened and what people were seeing.”. Either way, a conservative 1% IFR implies a 95% chance of 154,000 deaths or greater in the US alone. Tracking Rt also lets us know when we might loosen restrictions. 'Andari Illu', a house for all in Hyderabad. Take China: on January 23rd, they suspended travel and kept anyone from leaving Wuhan. Kevin Systrom Net Worth Social media is a relatively new phenomenon that has made a big impact on many people's lives. will reduce far more quickly than the model expects. The company says it regularly meets with media outlets. Systrom quit Nextstop after deciding to try and grow Burbn, and just two weeks later landed $500,000 in seed funding from Baseline and Andreessen Horowitz. While it’s unlikely customer count would stay the same for this period, the graph is instructive. In 2010 we launched and 25,000 people signed up the first day. We’re all learning and making it up as we go along, in the best way possible. Note, however, that “under control” does not mean good. Think of δ as how quickly people distance themselves from others. At the same time, Systrom and business partner Mike Krieger developed Burbn, an app that featured a check-in service, planning capabilities, photo-sharing and point-earning system. Here, I’ve plotted states where the high end of their HDI is less than 1.1. After Google, Systrom went to work for Nextstop, a San Francisco-based location recommendation startup. Assume every individual is in one of three states: susceptible, infected, or resistant. This isn’t just opinion. There are two parts: These two facts are important, because they unlock the ability to compare infections that happen at different places at different times. Initially rebuffed by Instagram co-founder Kevin Systrom, who wanted to build his own company, Mr. Zuckerberg revived the talks on April 5 of the following year, just as Mr. Systrom … In this case, I sincerely hope he’s right. When they do bend (China and Korea), it has taken draconian quarantines, mass surveillance and mass testing – none of which exist in the US. The US just crossed a dangerous threshold, Every infected city/area develops independently, tracing its own curve along the way. As discussed, we assume = 1/9 (9 days of infectiousness). Even once these measures are in place, cases have taken over a week to flatten. After observing real data, it returns distributions for the unknowns. On the one hand, some pundits argued cases would whimper out within a few weeks. The average Starbucks sees roughly 500 customers per day, so in a busy city let’s double that and assume 1000 customers per day. Post author By Kevin Systrom Post date March 24, 2020 Today, Dr. Deborah Birx, the White House’s coronavirus response coordinator said something you should hear: To fix this, I made one significant change to their algorithm that maintains the integrity of Bettencourt & Ribeiro’s original work while allowing us to see the real-time picture clearly. The flu has an R0 between one and two while measles sits in the high teens. I also wanted to figure out a way to explain how uncertain I was about that model being right. Regardless, you should watch these states over the next week. Kevin was born on December 30, 1983, in Holliston, Massachusetts, United States. For purposes of illustration, say the average person in NYC has about 250 people in their personal network. After a series of cases linked to China, Italy’s cases grew quickly.
