IF your goal is to work for google, facebook, Amazon or Microsoft, then yes, Google is a great place to be.

But if your goal is to work for next decades google, Apple, etc, then no, Google is not the place to be.

Start working on Bitcoin. Start working on Ethereum. Get to the cutting edge.

Everything you do at google right now is about 10 years out of date (and I'm including machine learning and all their "cutting edge" AI stuff) and targeted at supporting their existing established business.

Take this from someone who has been on the cutting edge for 30+ years-- the challenge for most people is that the cutting edge changes, and you have to be paying attention to follow it... by the time you learn mobile development, surprise, there's bitcoin! (as an example.)
