This dissent is well justified. AR glasses are a very dubious solution looking for a problem (that also bring up a lot of their own problems). Modern phones do so much and are totally ubiquitous. In the design of consumer electronics, it is hard to find a really compelling answer to the basic question: "why not just do this with a mobile app?". There is no need to commit to the tooling costs without a decisive need to have a piece of hardware built. For AR glasses, all the answers to this question that I have seen strike me as being sub $1000 dollar answers (would do it for ~$300 but not $600). Informally I can say that among people how are paid to use AR headsets (i.e. they are given one for free by their work and are paid 6 figure salaries to make them useful) usage is minimal. Senior executives on these projects are generally oblivious to the challenges and only wear these things at major meetings. Designers work with Figma and photoshop more than blender and frequently don't even check their designs against the optical issues of the displays. Engineers start spinning up byzantine projects for new Operating Systems because why not. The only people who consistently wear and use these machines for more than 2 minutes at a time are the prototypers. And while they are indeed serious users I have a hard time trying to parse whether they are just having fun playing in a world class sandbox or whether they actually think these are useful devices (Prototypers are the only people in tech companies who really seem to be having fun. In general they take a pay cut to work on projects that are just more enjoyable, and they frequently have bizarre hobbies that include buying niche produces like depth cameras, microscopes and GPUs just for fun. Not to dismiss this activity, but I'm not sure if they are really indicative of a broader need).
