While I don’t necessarily know if this is true or not, important to remember that the first demonstrations of multi-touch were given to Steve Jobs and the rest of Apple on an absolutely massive tech-packed table and its own room with a massive projector on the ceiling showing it’s contents.Pure fantasy. This system will never be the size of glasses. Never.
And this was the early 2000s.
just within that decade, they were able to shrink all that down into a phone, and later a watch sized iPod nano.
So I’d suggest saying something will “never” happen, especially when it comes to getting technology smaller and more power efficient, is stupid.
No one knows what the 2030s and the 2040s and even the second half of the 2020s will bring.
