Google has become a utility company, and I believe that's what you are saying. And I agree. I love Gmail, photos, drive etc and I have been a Google user longer than I have been an employee. This is a good thing.
But, I started my career at google, and can tell you with confidence that it is not the best place to build a career, especially if you are a high performer. Google will shape everyones career around average, and will not do much to reward extraordinary contributions, and it shows up also in compensation, promotions etc. google will happily not promote people unless they ask for, and many will not.
