AWS's mindset is software is useless without customers. Google doesn't seem to have the same care - it's a charity for academic software engineers to spend AdSense revenue on abstract high level computer science problems not caring about practical applications.
It's why most Google X ideas flame out. It's why there's a new chat app every year.
But - it's a net positive for humanity. Google publishes a lot of papers, and I think genuinely has moved humanity forward in the last few decades.
I don't have a PhD and I don't do L33tcode, so I don't think I'm smart enough to be at Google, but honestly I don't know if I would want to be.
I prefer shipping.
