Many people make the assumption that technology will keep advancing in a linear fashion. But it doesn't; it goes up and down like a wiggly sales chart, generally progressing, but not always. Many ancient civilizations became quite advanced, then collapsed. We're already starting to run into limits in some things. Just because cars could only go 60 mph in the past, but can go 200 mph now, doesn't mean they will go 1000 mph in the future. It's possible we may never truly understand the galaxy or be able to travel around from star system with a FSD, but that's ok with me.
I'l be Honest with you, its not ok with me, I will not experience even a landing on Mars, i'll be dead before.

But thats life...
It's very intriguing for me to speculate what is out there, what is far away, how many GALAXIES, and so forth, it is just so many questions and so few answers, and so immense distances, they are surreal, even some planets are surreal (Youtube, Planet size, watch)
its mind boggling, I would want us to go one day, to spread out there.
Is there life out there, of course there is, but we may never see it.
These are some of the things that make my play Elite, experincing our Milky Way , the only way I can
