Then they work backwards, trying to figure out some economic engine to make it happen. "Data centers" are (A) in-vogue for investment right now and (B) vaguely plausible, at least compared to having a space-casino.
But the demand / economic viability just isn't there. VR is cool but it's not mainstream. "Metaverse" exists and some companies are making good money off of it (Roblox, Fortnite, MMOs, etc), but nobody wanted Facebook's multi-billion-dollar-invested version of it because they just don't get it. I really hope all this nonsense collapses sooner rather than later and we go back to realistic and viable spending.
Large investments don't translate to results.
