Google is winner? What do they do now? I don't remember being excited about their product for a long time. 2008 if you exclude Android. Seriously. Gmail inbox partitioning was a good thing.
I would credit driverless car as a success of Google, imitated by many. They have failure too, fiber for example, and Google Plus.
Microsoft had also the big failure of Nokia phones, the results are mixed actually.
I wouldn't give any credit to Google with regards to driver-less cars. Tesla actually has product and software out on the market and infrastructure to support their ambitions.
