@spreporter - nothing stops them, but it won't be sudden or soon IMO . This is going to take time to get right [ if ever ] - because not all of their strategies work out. But the intent is shaping up. Make no mistake, Google will get there , one day.
I just don't see the investment at grass roots SEO going on as much with all this FUD. Best to focus on core business with overall digital enablement over brand, rather than Google, or you'll be left bare. Business has to stay relevant in what it does best, and digital publication isn't really a sustainable business model in the large verticals anymore. It's more sophisticated than that and anything with a technical edge can be overtaken.
It would be interesting to see how many acquisitions and projects actually sustain at Google as a statistic. I bet it's not a large proportion.
