It also doesn't have to be shut down entirely. It could morph into a form that doesn't work for a lot of people, but does for others (yet making meta more profitable).

Or stop being the place where we can communicate for free. Once profitability shifts to VR sets, virtual-asset markets and augmented advertising (or whatever markets emerge, if any)
