At Google it will be like going to grad school except you will be better funded, working with more consistently smarter people, and you will be getting paid instead of racking up debt. As a YCombinator founder you'd basically already be in the position that a Brown computer science graduate hop…
How exactly would you be racking up debt as a computer science Ph.D student? You don't pay for tuition, you get paid a pretty decent stipend + health insurance and you probably will do many industry/research internships (where you get paid very well). I say this with experience, as I am a CS Ph.D student and make more than enough to live on with a modest lifestyle and I have no debt. Plus if you get an outside fellow…
I'm not saying doing a CS Phd program is not worthwhile- it still is. But, if you have an existing offer at Google or YCombinator its like going to the NBA straight out of high school. Certainly there are good reasons to go to college. But at the end of the day, if the NBA is where you're trying to get to- you take the chance when the opportunity presents itself. Grad school will always be there.
