But is there much of a demand for it? VR has been a feature of video games for over a decade now, last time I used it I thought it was good enough (that was 6-7 years ago), technology wise. But it's nowhere near as popular as e.g. regular displays.

Any movie depictions of VR are fully immersive - Ready Player One (at least the film) takes some liberties in depicting the game world as if it's immersive, even though the guy plays with VR glasses and force feedback gloves/suits, all current-day technology. Most others have a direct brain interface. Some (Star Trek) model a realistic immersive environment around the player, but both of those are very much science fiction still.

There's some brain / tech interfaces, but if I recall correctly the brain has to learn to handle the signals first, there's no way to create a perfect, instant link.

Meta alone could have solved like 50% of famines/heavy malnutrition currently happening in the world if they used their metaverse budget to do something useful. And they'd still be so rich they wouldn't know what to do with the leftovers.

No one "needs" to push for that bullshit metaverse, the real world isn't shitty enough, yet, apparently they're dead set and achieving that, for people to wish to live in a computer.
