Facebook has epic amounts of user-generated imagery and text, and incremental improvements in NLP and computer vision generate incremental revenue (and profit) because you can put up better ads and introduce new features like translation. As an investor, that is very appealing.

There's no incremental revenue from Metaverse. It's a huge money pit, with no obvious end date for when enough billions have been wasted to call it quits. It could well work out, but if I'm an investor why would I want to invest in this through Facebook rather than through a bunch of startups pursuing a diverse set of strategies.
