There is a cheesy movie from Tom Cruise, Minority Report, whomever takes those displays to market, finds a scalable profitable way to produce them, finds enough courage to resist status quo and find massive product market fit, will be the next Jobs or Musk. Idea wise, everything literally was on either Star Trek or on Star Wars previously. I know these personalities are not exactly likeable but we'll keep this conversation for the next simulation of the universe with different parameters...

gorilla arms are a thing you cannot dream your way out of. While a display projected 'in air' is cool a standing gesture based ui is very much not.

Brain-computer link bypasses the gorilla arm problem entirely.

What if we think those displays as VR headset alternative? I feel it could be hugely helpful doing surgeries/repairs don't you think? Direct brain connection means too many cmd-z's for me.
