Individual geniuses create peaks, while systematic teams create indices. Top developers, traders, and even investors (such as Elga Gill as a solo VC with a fund size of $1b+) are often typical of going it alone. But if your goal is to establish a long-lasting business, you need to gather a group of people to jointly create higher-level wealth. That's why you need to establish division of labor balance (development, trading, and risk control each have their own responsibilities), ability relay (to avoid personal state fluctuations), and risk hedging (different strategies complement each other), in order to convert personal profits into sustained compound interest. Buffett's early personal speculation and later Berkshire Hathaway system are the most typical cases - the former annualized at 70%, but with a clear upper limit on scale; The latter has an annualized rate of 22%, yet it has created the most enduring wealth snowball in human business history.
