I was thinking about the evolution of human-computer interaction.
Initially there was not, simply wire the program to be performed and the answer was expected.
Then the punch cards arrived, so still no interaction.
Finally the keyboard arrived, which is still absolutely present even today, maybe virtual.
Then came several devices, optical pens, mouse, trackball, touchpad etc., but let's say they are more of keyboard shortcuts rather than real substitutes.
I believe that current designers suffer a major constraint given by their experience, as is natural, and that they can not think freely, and invent a new way to interact with a computer.
So I ask you, to think in a free way, without constraints, talk to me about how the human-computer interaction will be.
