One possibility is diversification. By and large each successive tech iteration resulted in one big winner: Microsoft (operating systems), Amazon (e-commerce), Google (search), Apple (mobile), Meta (social networks), Netflix (streaming), and depending how you look at it, Tesla (EVs). If you invested in one of these companies early, you'd see a huge profit one or two decades later. The problem, of course, is that you don't have a crystal ball. However, if you invested in these companies and a few of their peers in the early days, then you lost all the money in their peers, made a lot of money in these companies, and you are still well ahead in the game.
At this point, if you don't know if Anthropic or OpenAI or Mistral will be the ultimate winner, you invest in all of them. Of course, there's a chance that another startup comes out of nowhere and all your investments tank, but nothing is risk free in life.
