the fact that founders of ai labs so regularly leave the companies they started, often within months is raising or not long thereafter before anything has really happened, should somehow register as a reward signal that:
a) you should think really hard about your motivations to start a company
b) doing so should be because there’s just no other vehicle for you to express your talent and conviction on bringing something new into the world and doing whatever it takes to win
c) you have to sure about your choice of cofounders, come rain come shine
otherwise, just don’t do it, and that’s fine!
