I think the issue is even at $50 it won’t sell well.
Because nobody wants to strap a pair of goggles to their face to compute.
I say this as an owner of the vision pro.
It’s getting old. Whenever a new technology emerges, a lot of naysayers start to argue, why that specific technology is bound to fail. Often times they claim to speak for everybody and won’t accept any opinions deviating from their own, because they have the absolute knowledge.
Happened with Apple Watch, iPhone, AirPods, cellphones, home computers, TV in general, cars (100+ years ago it was combustion, nowadays it’s electric) etc. etc. History repeating.
Will everyone on this planet want to have such a device? Surely not.
But even the 1st gen found buyers in the 5- to 6-digit numbers (not even counting in competing products of other companies). That's definitely more than “nobody” already.
Now let the price get into more affordable regions and the technology mature (esp. size/weight/comfort and motion sickness) and more people will get interested. Be it for the atmosphere and convenience in games, movies, sport events or maybe even pr0n (which is known for its ability to mobilize masses, re: VHS vcr format).
I know that I’m interested for sure!
And I’m convinced that it will eventually be perfectly normal to wear some kind of smart glasses every day, even in public. The younger generation will then mock the older generation that still tries to hold tight to their familiar tech slabs a.k.a. Smartphone, just like some elderly people today prefer a dumb phone.
It will probably still take 10+ years for smart glasses being well established in the mass market, but the potential of that tech imho is huge!
