NFTs are dying and link rotting. ICOs are out of fashion.
VR is back in its niche.
3DTV .. I've not seen that marketed for quite a while now. Things that are fads will die out eventually.
Crypto meanwhile is in an odd space: everyone knows blockchains are too much of a hassle and that the volatility is too high, so they're using centralized exchanges and "stablecoins" (shadow dollars). There's still a huge amount of money there but not quite as much as the stadium ads / FTX peak.
I wish you could still buy 3D TVs. Why? We used them to build a truck simulator which had a driver and passenger. The view out the window is different for each person. They were perfect for that, but it's too small a niche to keep making new TVs.

Its probably coming back in a few years via lightfield displays, though for some reason Google seems to think the killer app for those is videoconferencing.
