I totally understand what OpenAI and Google are trying to do with AI but I never understood Meta's angle.
What's Meta's AI product?
This is part of a pattern of tech leaders investing in order to avoid getting shut-out of whatever the next paradigm of computing is supposed to be.
- Google building Google+ and stuffing social into everything to avoid getting shut out of social networking. (The fear Larry/Sergey felt about this is why Vic Gundotra could bully and survive scandals until it became clear that Facebook wasn't an existential threat/Google+ was not going to really compete)
- Meta attempting to build an AI assistant because they were afraid Alexa/Google Assistant/Siri would be how everyone accessed computers in the future (due to technical failure, this product only ever launched as control mechanism for Oculus, but the ambition was larger)
Of course this always come alongside other factors that lead others to follow when a new concept is proven; however a tell-tale sign that leadership is worried about market dominance rather than a mere new line of business is that they spend or throw weight around above and beyond what the new line of business alone would justify.
