These technologies really do solve problems for some people. Ignoring the temporary problem it’s solving for most-everyone right now, VR lets quadriplegics and house-bound invalids go places that aren’t accessible, e.g. the middle of the jungle. And VR is also useful for assisted visualization in the treatment of PTSD and other associated disorders.
This is also the thing that everyone who makes fun of those “as seen on TV” products needs to be reminded of: they’re not really for you. For many products, there’s a smaller core of people who actually need the product, and then a much larger halo of people who might want the product if you sell it the right way. For the As-seen-on-TV products, the core market is usually “old people who don’t move around well, or have the grip strength/dexterity necessary to operate hand tools.”
But even the core market doesn’t like being advertised to in a way that points out their problems. They’d rather that you wrote your pitch to target the larger halo market, and then they will see that ad, and notice the particular benefits to themselves as a core-market member.
So in the end, you get things like the ad for the Snuggie (whose real point, IIRC, is that it’s a robe that someone can put on an infirm person without having to lift them to get it around them) that instead markets it as a sort of weird throw-blanket with arms; or ads for VR headsets that market them as being for Beat Saber. In both cases, the advertising is ignoring the core market with a need for the product, knowing that they’ll discover it on their own once they see the advertising aimed at the larger market.
