What makes you think that more artificial stuff is going to reinvigorate the business? Metaverse was supposed to be such savior, but this time they didn’t even rename the company…
Also, the business doesn't need to be reinvigorated. It is booming and they are investing in places to stack more gains down the road & cement current status, which investors like to see. Many big techs right now are flailing and trying to artificially keep profits up by slashing costs only and not increasing revenue, which dents innovation. Meta is managing to sink money into AR/VR AND AI while seeing big revenue growth.
