Could we just send frozen embryos of humans and then have the ship auto thaw and gestate them 16 years to arrival?

With another 2-300 years of technological progress this doesn’t seem outlandish mission at all.

that sounds highly unethical. none of those people agreed to go on the trip

did any of us agree to go on our current trip? I do see your point but I think eventually humans might do it.

Meh. 200 years aro they would have called you insane for wanting to fly between continents, let alone to the moon.

They also would have called you crazy for saying you wanted to turn lead into gold with alchemy. Fact is, most of the time the people who say something can't be done are right.

Nitpick: we can actually transmute, either by fusion or fission. Sure it's not economically effective, but then neither was Apollo.

Yeah but they don't matter. All the trying was worth it, because I can fly halfway around the Earth for a few hundred bucks now. If in a different world I got gold out of lead but no airplanes, it would be fun too, but in a different way.

If the no-sayers really won and nobody tried, we would have neither.

> They also would have called you crazy for saying you wanted to turn lead into gold with alchemy.

Which is doable but exceptionally expensive.

Not a strong argument against the ship unless you're calling it a waste of money.

Of course we’re far from it, if ever possible. I was just being playful on the whole premise of “colonizing” another earthlike planet

Oh, I'm not bashing you at all. You're absolutely correct. You bring up extremely important things to realize when discussing space travel. Especially long term missions. Political will being the reason why these missions haven't happened, as someone else mentioned, is total crap. It's just an easy excuse to not think of ACTUAL consequences and live in a scifi fantasy.

Yes I agree, we seem to be working on the wrong problems or get the priorities wrong. We keep on inventing newer technologies which come with newer problems while the ship is slowly but surely sinking. Sometimes I wonder what would it take for all of us to join a concerted effort to concentrate on the real problems we have. Technologies seem to veer into an escapist route, some way for us to run away from the problems we do have: virtual reality, leisure space travel, AGI, synthetic life, immortality.. I hope we'll eventually wake up in the last hour, at least to acknowledge where we've gone wrong.

I think this is exactly why there's an apocalypse fantasy/fetish. It's in our psyche that we're all focused on... well... dumb shit. A post-apocalypse lifestyle makes you focus on what I think we can all truly appreciate as important. There's a lot of interesting studies done on localized disasters where the idea of community actually erupts out of it. People working together and sharing, regardless of their "social status". It's all short lived until the outside world aid arrives and you still get a few bad actors in the mix (though it seems statistically, no where near as many as we think). Generally though, it takes hell on Earth for us to regain our "humanity".

Not trying to be edgy, but I think a lot of society problems stem from more and more globalization. When you're less than a drop in a gigantic pool of people, it's hard to feel like anything matters. Not saying the closed off, nationalism system is any better in the long term. It's just hard to determine a balance to the system. And with that lack of balance, we run away into the escapes you mentioned.

Sigh... well, I just ruined my day thinking about this crap again.

I have a similar experience from my childhood. I grew up under communism in eastern europe and I remember the crisis we were going through at the time, food was rationed and there were long queues everywhere. People were even joining queues without knowing what was being sold and some would start lining up overnight. I was a kid back then and didn't experience the adversity first hand but I could see and sense what was going on. Aside from these things, however, I remember how helpful and inclusive the community was. People were sharing whatever they had, whatever they cooked, recipes, anti-establishment jokes, books, video tapes, etc. There was this sense of belonging that now has dissipated completely. I was struck with a deja vu when I visited Cuba a couple of years ago. People are poor but are sane and happy in their own ways and they have time for one another. There are still disparities but not like in a western society when one counts their pennies and the other their billions. Romania, the country I grew up in, has been engulfed in corruption and asides from a cities with large concentration of wealth, everything is in disrepair, the community disappeared almost completely and everything seems to have gone downhill for the past 30 years. In no way am I decrying the communism, it was brutal to many, but what has ensued after the fact was a veneer of shiny nothing.

So, I was born in the USA, but my parents are from Poland and left a few years before the collapse. They shared many similar stories with me over the years. Generally, when the environment is bad, the local people are good. But the reverse is true too. When the environment is good, people tend to suck.

It's weird to be honest. A lot of books/movies think utopia arises in the land of plenty. But I guess a real utopia is where we all suffer against a common threat/enemy. That's when we're most human?

But when it comes to communism, it does have it's upsides. Like now in Venezuela, almost everyone is equally poor as shit. Thus, criminals don't rob people. Bullets cost too much money compared to how much they can rob from people, if they even have anything. That's a win... I guess. Great way to stomp out crime. Make everyone too poor to even bother robbing.
