If a sci-fi’s technology became incredibly mysterious in design and increasingly life-like, could it evoke the same impressions as fantasy?

Answer 1

Oh, no. No, it couldn't. Sorry. There's just no way that could happen. No way at all. Hope this helped.

Answer 2

Basically, you're asking if Clarke's Third Law is correct.

I think it is.

In fact, there are "fantasy" novels that turn out to be SF because the "magic" is really very advanced technology.

And you don't have to resort to fiction. Imagine what a person from some hundreds or even thousands of years ago would make of the world we're living in today.

I guess, to people from a few centuries ago we'd look like wizards; to people from millennia ago we'd look like gods.

Yet, of course, we're none of that. Hey, most people have no clue about the underlying technology of the gadgets that they're using.
