He’s got one of the biggest free cash flow machines in the world, so he’d rather swing and miss than not swing and be left behind, given that with $200B top line, there is essentially no financial penalty for a swing and a miss.
It does look goofy to have made such a big gamble on something as stupid as Metaverse in hindsight, though.
