You could probably get an incredibly sophisticated AR system using a big brand new workhorse of a GPU and a fancy camera if you don’t mind wearing a 5kg skullcap, but you won’t be walking anywhere with it so you might as well just get a cheap 2nd/3rd/nth monitor and another HDMI port.

I wouldn’t be surprised if the hardware is compact enough for on-the-go semi-reliable AR in 10-15 years, but there’s probably a lot of more complicated issues than moore’s law such as batteries and thermal issues
