Maybe, but being right once doesn't mean they're never wrong again. It's hard for me to see how Google wouldn't have been better off buying Skype and integrating it into GMail. Easier said than done for sure but a hell of a lot easier than getting Skype users to switch to Google Voice. Also, last I checked Google Docs still wants to save things as files. I guess Pichai never had to at least prove his idea correct and justify his decision. Maybe these guys are good product managers but they seem to be pretty bad at strategy. The point I'm making is that they don't seem to have been held accountable.
