Humanity’s greatest journey so far has only reached the closest world to us: the Moon ... in a universe that stretches endlessly in every direction and is seemingly infinite.
It's kind of wild to think about: we might end up collapsing our own civilization before we ever make it beyond our solar system.
At this point, I suspect the next real explorers won't be us, but probes carrying intelligent machines..our robotic descendants venturing where we can’t.
Many see this as the answer to the Fermi paradox. Any society on the path to being advanced enough to potentially leave their system probably gains the ability to destroy themselves before getting to that point.
Short terms issues preventing long term gains.
That is one answer. Another possibility (the one I prefer, since this is mere speculation anyway) is that we are early.
We could be late too, it hasn't even been 200 years since we're technologically capable.
The universe is physically big, which means we'd have a hard time finding life even if it was going on at the same time as us, but add time to the equation and it's game over. There could have been a star trek tier civilisation next door that died 1m years ago and we would probably never know

Early as in we may have developed before any other civilizations? That's interesting. We're speculating of course, but what would explain us being the first after so much time – 13.8 billion years?

If there isn't a good rationale why it'd be applicable to every civilization that has ever arisen, then it isn't a good fermi paradox solution. Otherwise, if even 1%, or 0.1%, don't fall into the same trap, the galaxy still ends up completely colonized.
One (terrifying) option is we are alone. There is no real reason to believe life is abundant in the universe. Even on Earth (the one place we know for sure can support life), life has only occurred once. Life may just be so much more rare than we think is possible.

We don't actually know that at all. It could have happened many times and one line won out, it could have been more of a diffuse process than a single event (picture how microbes share genetic material ~freely but even less structured), or there could be a ton of life out there on Earth that's from a completely different tree. We really have very little idea what's living around us.

Any manned mission in the next 100 years or so to the surface of a moon or planet is basically unnecessary and just to show we can. I am not saying this is a bad thing - but much of the reasons we haven't had manned missions is because it isn't worth it. Robots can do most of what we can do already and what they can't we can do remotely. There's really not a great science reason to send people with our current technology. Robots are already the real explorers.

I've never felt this impulse. To me it's like saying the Earth is 8,000 miles thick but we all chose to live within just a few feet of the surface.
Yep. Ghost in the shell. The robots are just the next stage in the evolution of life..
"we might end up collapsing our own civilization before we ever make it beyond our solar system."
Given what I see in the past 15 years, I don't particularly see that as a problem, honestly.
"Some say it has already happened..."
Lol
Both Voyager space probes are way farther away than the moon. Is this a reference I'm not understanding?
Parent poster is considering only crewed journeys, surely.
