The Oculus quest 2 definitely has fit that bill. It has game console level sales. How truly useful and confirtable it is may be questionable, but it certainly supports a market.
Nerd dads are famous for buying anything that might run an NES emulator, then not using it after it turns out their kids have better things to do than listen to square waves.

I did that to play around as I was playing with 3d programming and I'm a nerd.
And while friends and family know that and a few tried it out for a little bit and liked it, no one cares.
Which is fine but it is a gimmick.
I was hoping it would get more traction with real life training like how to use a lathe but nothing really came out or is in some internal companies.
