Earlier quoted context omitted.
Google has a long and successful history of acquisitions, as also a long history of lack of direction and headless actions even in their youth days. It's probably just natural for a company with too much money to invest that way.
What long and successful history? The only one that I can think of that was a definite success is Android. Their only notable hardware acquisitions that I can think of were Motorola which was a disaster, Nest which is barely muddling along, and the semi-acquisition of HTC’s hardware team that made the Pixel. While the Pixel may be a great phone, it isn’t taking the world by storm
Those have all been industry defining.
