Those kinda exist already. Even Realities G2s, for example: no cameras, built in subtitles and live translation and navigation on a discrete minimal display, open source SDK. Expensive and not quite mature, but that’s a perfectly defensible device to be wearing IMO (they do have microphones. So does your phone)
Absolutely will, lot of financial institutions still need to finish offloading their shit on the rubes and they need another big IPO for that. All bets are off after that though
