Alexa is to Amazon what Metaverse is to Meta. Both are bets to create a new platform as they feel threatened by Apple & Google's dominance on mobile. Meta should take note. Alexa is widely adopted (# of devices) but has little engagement and still hasn't broken outside of the most primitive use-cases (play music, remind me, etc)
Meta tried to create a new market with the Metaverse, but Amazon overhired in their Alexa department because they were surprised by the financial success of smart speakers and wanted to double down.
Anecdotally, I often see the trashcan speakers in peoples' kitchens, even if people usually say that they only use it as a fancy radio alarm clock.
I rarely meet people who have tried Oculus' recent hardware, and those who have are usually gadgetheads who keep it in a closet as a party novelty. There was a spike in interest when Valve released the Vive and Oculus was an independent entity, but that was more about gaming than social experiences, and it seems to have tapered off in my social circles.
