>the metaverse is a giant smelly pile of poo and he sunk millions in it

He sunk tens of billions.

Estimates (because we don't have "Reality Labs" broken out before 2019) put Zuck's Metaverse Misadventure & Boondoggle about $75B in the hole ($10B revenue on $85B spend) with no signs of a turnaround in revenue.

There are plans to turn things around with AR spectacles but decent ones are years off and will require entirely new investment with little re-use of that $75B Metaverse nonsense (Oculus acquisition, 5 generations of Quest R&D, Horizon Worlds, partnered and sponsored games and content, etc.)

The only real ROI will be the experience and staff gained. The rest will almost certainly land in the dustbin.
