I am both a fan of blockchain and VR. I also have a strong cynic inside of me that trashes on both of them whenever it can. It's fun being me I suppose :)
Blockchain is IMO in a much much much more questionable state of relevancy and usefulness than VR.
Why?
I workout in VR (supplemental workouts by playing Eleven Table Tennis to the max).
I boardgame in VR (Demeo).
My GF picks up my headset and plays Beatsaber.
You can have multiple screens in VR. While I'm not the biggest fan of them, I will be if I'd travel to another country, not being able to bring my monitors.
Oh, and I've convinced quite a few of my friends to do the same (workout, gaming, productivity).
VR is already here mate. People game, people exercise, people get new experiences by watching VR videos (I got better at skiing because of it), people are using its productivity apps to design stuff (think about designing game in Unreal Engine using VR). There are certain use-cases in which VR outperforms anything else (and in most use-cases it doesn't).
VR has tons of uses!
It's not perfect by any means, but we're slowly getting there. 4000x4000 per eye is the hallmark I will be patiently waiting for. Better omni-directional threadmills are something I will hope for. We already are beginning to have haptic feedback suits from owo. I'm not a fan of haptic feedback suits, but others are.
VR is here to stay. It won't replace anything, it will augment how we are going about our daily stuff.
Whereas with blockchain, well, it's mostly used for speculation and I still haven't seen people use it as a legitimate currency. And this includes myself! Like, I used bitcoin to buy a bitcoin wallet, but does that count? I don't think so. The current use of blockchain in terms of cryptocurrencies is speculation (at the moment) and I am hoping it will change, but I wonder if it ever will. And I am a fan of the whole thing, but let's not kid ourselves. I hope the unbanked will use it. I hope people in super high inflationary countries will use it (because as volatile is bitcoin is, it beats any currency with hyper inflation). Unfortunately, I don't have any insights on the unbanked.
