The Apollo moon landings were like real-life sci fi. The culmination of the space race between super powers doing stuff from way into the future. It had been building for years and Apollo 11 the crescendo.

We'd only just got a land line and we watched 2 guys walking on damned moon on B&W tv!

Modern tech has to an extent inured us to amazing stuff. We have the attention span of gnats driven by culture and media. Someone does something clever with a computer a phone ,software or whatever , we go, that's clever and tomorrow its old news and we're excited by something else.

We now expect amazing.

Everything is wrapped in hyperbole and there are so many others things for people to do and see now.

It is hard to imagine anything that would make the world stop and go wow! And that wow lasted for quite some time.

Successful nuke fusion , faster than or near light speed travel. Detection of aliens or alien signals of sorts. Meeting a tourist from the future or past perhaps.
