This question is argued over and over again the AVP forum. 🤣 A lot of people seem to be offended that the product even exits. I think that is due to numerous reasons, including people being priced out, people who assume (wrongly, I'd argue) it forces isolation from the outside world, and people who are set in their ways and think "I don't understand this so it's bad", and maybe even some unconscious anger at getting older.
As one who uses it daily, I absolutely think this is the future of computing. I use it for hours a day, and am more productive because of it. In my case it has definitely already paid for itself (a large part of my job is writing proposals for new business and being able to isolate myself while working from home a feature for me, not a bug - I was looking at renting an office and now I don't have to). Others will tell you I am crazy, I don't use it for "real work" (whatever that is), and the product is a massive failure because it isn't bigger than the iPhone was at the same point in its lifecycle.
It absolutely needs to get lighter and cheaper before there will be mainstream acceptance (and OF COURSE Apple knows it needs to be lighter and cheaper.) I think it was a good idea to release it now, I am glad they did, if for no other reason to get feedback on how people use it in the wild, developers thinking of app ideas and building for it, etc. Personally, I think Apple WANTS it to be a slow roll, niche product at this point - they don't have the capacity to make a ton of them, and by the time the technology gets to a point where it is light and cheap enough for mainstream acceptance they expect more and better content, apps, use cases etc. But others will argue Tim Cook ordered Apple to release it without knowing how it would be used and therefore has lost his marbles and the product is a massive failure. I think Apple's leadership is smarter than the average MacRumors poster (myself included), but maybe others are right and I'm wrong.
I do think it will be a very big deal as it gets lighter and the price goes down. Not as a big as the iPhone - but absolutely has the potential to replace Macs/iPads, and that isn't even taking into account the potential entertainment possibilities. (Just think how much money people pay a month for a cable JUST so they have access to live sports, now imagine in 5-10 years you could have court-side seats at every NBA game, seats behind home plate at every MLB game, front row tickets to the latest Taylor Swift concert/Super Bowl halftime show, etc.).
But lots of people will tell you I am smoking crack and that it's already proven to be a failure and that normal people won't ever put something on their face unless it's like a pair of normal glasses (which I don't think happens in the next decade - if in my lifetime, and I'm in my 30s).
We'll see who is right - I hope I am, but I've definitely been wrong before and will be again.
