I'm excited about it. I'm a Mac user and have been waiting for a high quality AR device so I can use it for work/programming.
The first few versions will probably be a buggy, expensive toy and even though some people see AR/VR as dystopic (and it might be) I think it's the future.
There are many studies showing how harmful they are, and there are many showing they are not. A lot of studies were funded by tech companies. As someone who understand incentives, I tend to err on the side of caution.
And out of basic logic and knowledge of cell biology, never in the history of mankind we were exposed to such amounts of electromagnetic radiation so close to our cells (which essentially work by electric interactions). Radiation intensity is inversely proportional to the square of the distance.
My memory of doing a google review years ago was that the research was inconclusive.
I tend to agree with you though and ideally I would live by the precautionary principle. When it comes to work though I tend to accept the self-harm that's required to accomplish what I want.
I'm sitting more at the wait and see camp. I like the idea of AR/VR for entertainment and for use as new tools, but at the same time am aware of the possible dystopian uses. Will want to see other people's experiences with the product and also try the product myself before deciding upon it.
The device itself looks quite nice, and it might even be one of the best VR/AR headsets out there.
But that's a bit irrelevant.
The important thing is that Apple created a whole new marketplace, a new category of apps, and that ecosystem will have a chance to change things, just like they did with the Apple Store for the iPhone. They will probably force all apps and accessories to only work with their own branded devices, as they tend to do.
This might help create a new alternative marketplace for open source apps, etc, but I'm not sure about it.
