Unfortunately this is the case. I've seen it come and go with a bunch of technologies. Almost worse still is, if you go and ask these people ten years later about the same technology they promptly dimissed ten years prior, it's as if they never said it. Now that all of the things that you thought would come to fruition have come to fruition, they act like it was obvious. This goes for all sorts of technologies too.

I should think of a better example but even something as simple as online dating, went from people not seeing the point of it, to them using it, to some of them saying they don't trust the regular non-online version of it.

And even that example is for something that ended up being of concern for them, when you move on to things that are beneficial for broader humanity then there's that extra layer.

Nevertheless I think it's important to recognize that other people are in different spaces and live different lives. Whatever they don't realize yet will come, and we need to understand that there are broad things that we don't realize yet. Treating those people negatively (as somehow below us if it comes off that way in the phrasing), I think isn't beneficial.
