Neither? My prediction is the latter will retire coming up and have the next one clean the mess.

Personal opinion and jaded perspective of course. Disclaimer: don't like shortsighted "follow the shiny thing" decisions. I haven't seen evidence the CEO of Google has positioned the company for the long term or to survive. Namely, the bus would have been going fine if not better without some if not all of the Google leadership on the wheel.

I hope I am wrong.
