When I say skills you are limiting your imagination drudge-work skills. Skills could also be Tennis, Dancing, Sex, Golf.
Productivity could also be fixing your car, bikes, plumbing.
VR is one of the few technologies which both lazy and active people can benefit.
Unless you put yourself in the category of a neck-beard who doesn't like moving from your lazy-boy and also don't like porn, the category of people who won't benefit from real-life VR is very tiny.
Once something benefits them, People will jump through all kinds of hoops to get them
I think tech bros are way overestimating the interest of people in general. Nobody's going to train for sex or sport in VR, it lacks 90% of the experience.
People want to live real world thing, not evolve in a virtual world alone with appendices that barely mimic real life sensations.
A $300 VR headset has none of those barriers and is open to millions of developers and can constantly iterate.
Understand the difference and you'll become a better investor.
Else you are just falling for the Availability Heuristic Fallacy
And even then, not so many people care about being productive or to master new skills.
