The people who made those "world shifting" products at Google back in the day are long gone. Google is in the post-MBA-invasion phase where they are focused on value extraction from their market dominance and existing products, not in taking big risks and building big new things. i.e. They did a speedrun of the IBM playbook in record time. (Obviously I'm exaggerating a bit here, lots of good people still at Google, but the Google that made the products you're referring to doesn't exist anymore - look elsewhere for that stuff).
