If investors always need a little more information and none of them understand the product, then doesn't it make sens to have funds? Funds where investors would pool their money and where very smart people with very deep knowledge about he market make the investment decisions. Isn't that what VC funds are? So if VC funds are supposed to be led by people who know what to invest in, but it seems none actually do, not even Y combinator, then isn't there something else that pg did not mention? Could it be that simple, pure, dumb luck plays such a large role in each and every startup that educated guessing what to invest in is impossible? And doesn't that mean that the most rational investment strategy is the one of the index fund? Invest in everything, most will fail, a few will succeed. So does that make all investors just market inefficiencies?
