Random Walks

·3 mins
Life is a series of random walks. Even if you walk the same path every day (in the literal sense), your individual steps on every walk you take are essentially random, and for the most part you aren’t even conscious of them because this is handled by muscle memory. When I say the steps are random, what I mean is that if you could precisely measure every step you take—where your foot lands, how much force you apply with your individual muscles—the data would reveal a pattern from a statistical perspective, but each individual step would follow a normal random distribution. In fact, research on human gait variability confirms this, with studies showing that step-to-step fluctuations follow statistical patterns characteristic of complex systems.

My Worst Predictions

·7 mins
I’ve made my share of bad predictions. I’ve had plenty of good ones too. But being right often doesn’t matter, because few people will remember if you were right or wrong, and when it comes to placing bets on your predictions, timing is incredibly difficult to nail down. Some of my best predictions include my general bullishness on software and the internet since the 90s (when the dot-com bubble saw the NASDAQ rise over 400% from 1995-20001), betting on Airbnb (now valued at $86B+), and Bitcoin (up over 30,000% in the last decade). In the case of Bitcoin, I was right about the bet, but got the timing wrong. Bitcoin’s journey from $0.09 in 2010 to nearly $69,000 in November 2021 represents a staggering 76,000,000% return, making it the best-performing asset of the decade by orders of magnitude. For context, an investment of just $100 in Bitcoin in 2010 would have been worth over $76 million at its peak.
