In the early 1990's, DEC (Digital?) Cambridge was demoing a tablet prototype, with assorted Moore's law curves suggesting viability in early 2000's. Then there was the wait for a market to gel. When will software development get a screen-replacing HMD? One might manage it with existing parts for under $1k... but absent a demonstrated market, no one is bothering to build it. So maybe next year. Maybe more capable systems happen first, because some "companies will pay $10k for this" has a clearer market story. Market prediction is hard. As is some tech path prediction. But some tech changes are more predictable, and when those intersect clear and funded needs... some forms of prescience seem less hard than others.
