Sure, no doubt. But the arguments fielded on HN as to why these various technologies are dead ends and will implode once people become rational are weak. They're usually from people who literally have never used the technology (or, used it many years ago.) At best, they have, don't get it (which is fine) but then go on to make the leap that since they didn't get anything out of it, the whole thing is a house of cards. This is a similar error as thinking every new tech that comes along is going to be the next big thing.
The value prop of VR and AR is remote social presence on par with f2f and full sensory override. This is why Facebook is pivoting the entire company around it. This is not something to ignore and dismiss, unless you think Zuck is a complete idiot. The value prop of crypto is economic freedom. This is why VCs are pivoting their entire portfolios around it and why more than a trillion USD have rushed into it. This is not something to ignore and dismiss, unless you think the entire alternative Internet-based financial system being developed around crypto is a bunch of hot air. At a minimum, for those technologies, they deserve steelmanning given how far they've run without dying. The hubris it takes to dismiss things as big as these, which as much potential to radically alter society, isn't just unfounded, but foolish, given that being on the wrong side of this trade in the direction of dismissiveness is hugely risky if you are a technologist.
