Though I am not following it at all, I have the feeling that the mere name-dropping of a 'big vision' by the Zuck has unleashed a frantic activity in the market where many companies are rushing in to be early adopters and stake their claim shoud there be any real uptake in the future.
I've seen quite a few corporations spending big on Metaverse ads for instance, where they announce techz they are working on.
Of course it may all just fail and be vapourware.
