Nvidia is tied down to support previous and existing customers while Google can still easily shift things around without needing to worry too much about external dependencies.
Google will have no problem discontinuing Google "AI" if they finally notice that people want a computer to shut up rather than talk at them.
how you define big? My understanding they failed to compete with facebook, and decided to redirect resources somewhere else.
The hype when it was first coming to market was intense. But then nobody could get access because they heavily restricted sign ups.
By the time it was in "open beta" (IIRC like 6-7 mos later), the hype had long died and nobody cared about it anymore.
I and a lot of other googlers were really confused by all of this because at the time we were advocating that Google put more effort into its nascent cloud business (often to get the reply "but we already have appengine" or "cloud isn't as profitable as ads") and that social, while getting a lot of attention, wasn't really a good business for google to be in (with a few exceptions like Orkut and Youtube, Google's attempts at social have been pretty uninspired).
There were even books written at the time that said Google looked lazy and slow and that Meta was going to eat their lunch. But shortly after Google+ tanked, Google really began to focus on Cloud (in a way that pissed off a lot of Googlers in the same way Google+ did- by taking resources and attention from other projects). Now, Meta looks like its going to have a challenging future while Google is on to achieving what Larry Page originally intended: a reliable revenue stream that is reinvested into development of true AI.
The only lunch that will be eaten is Apple's own, since it would probably cannibalize their own sales of the MacBook air
