* How uncomfortable the headsets are to wear for long periods if time
* How useless they are (what are they solution for?)
* How ridiculous they look
* How expensive they are
* How expensive it is to produce content for
After they solve these issues then I will worry about the dystopia we are in. VR headsets may look cool and futuristic in the movies but in reality they are just screens you wear on your head and that's it.
And they won't be useless! That's the worst part. They will provide compelling value, like smartphones, and as such will be impossible to boycott. At first the value will be simple, obvious utility, like route overlays. Later it will be value within the system, much like how the main utility of smartphones now is to run the mandatory apps to participate in aspects of society that previously did not require a smartphone. And of course they will be addictive.
Here is a short sci-fi film depicting what I fear: https://www.youtube.com/watch?v=YJg02ivYzSs
Now as far as making them more useful I suppose *if* they can solve that first problem plus make them match the form of IMAX glasses (preferably smaller). Then yes they could be useful (providing there's good enough applications).
But don't cause the user to get sick feature is not 'a nice to have' you can't expect it to spread like the smartphone if people can't use it for long periods of time.
Will Meta solve that problem? Doubtful. Will they provide good enough applications to make AR worth using once they do? I wouldn't bet on it.
Just because a company has an incentive for something to be successful doesn't mean they can pull off. Just look at metaverse.
