Yeah, I do mean lower risk and higher rewards. Generally pepple think it's like buying Pfizer before they release a vaccine, but it's too late by then. Something like buying Nvidia during the crypto/AI boom, or OpenAI after they released GPT-2.

Y Combinator plays on the very high risk tables, but they get in early enough to also reap very high rewards for a relatively low investment. And they've specialized enough in it to lower the risks.

Berkshire Hathaway does the exact opposite, they specialize in finding ways to get the risks so low that the lower returns don't matter so much.
