The web is way more mature right now than 20 or even 10 years ago. There's way lass untouched niches waiting to be filled by the new killer product. And Google already owns the search market, the ads market, the smartphone market, the email market, the browser market, the maps market, and soon maybe AI market, etc. What new untapped multi billion market is left for them to conquer? The pond is already fished out at this point. So of course most Googlers are gonna have to be factory workers keeping the factory running instead of dicking around creating new useless things that bring in maybe no significant revenue. The days of Google & Co. spending billions on pipe dreams is over for now.
Innovation is at start-ups which Google then buys because it has ad revenue. People go to work at Google because it pays well and less headaches than working at startups, not because they're gonna invent something new.
