Anyone know the answer?

I think that's correct.

I remember at the time it seeming incredibly forward thinking, and I seem to recall articles going nuts about the cool things in it, speculating if they'd come to pass. Years later, it's said that this movie had more things that had actually come to fruition than any other modern scifi film. (gesture control, notepads, bluetooth-looking ear phones, etc). Wish I knew where I read that.

If you're ok with visiting imdb, the trivia section has a bunch of insight into the technology used and mentions the people Spielberg used as advisors. I remember an article at some point about how Apple was working on and had patented a similar see-through giant screen with swipe, magnify, etc., that wouldn't require touching.

I did find the desktop computer at his desk to be surprisingly dated looking. Still have a keyboard? Eh, they'd be long gone. Maybe a projected keyboard, but not this thing.

Yes.

Though I bet someone can name an older movie or show where a transparent screen of sorts is seen (like a map in the original Star Wars). But a remarkably futuristic transparent display screen that’s interactive like in Minority Report? Doubt you can find an earlier example in a movie.

The way Minority Report showed this technology was groundbreaking.
