I started paying for chatgpt pro.

Yeah, I very quickly realized it was still a filtered product nowhere near as magical as it was in early December.

I need an unfiltered model of similar capability - gpt 3 is close but not quite there.

I’m not the OP, but…

I guess it depends on what the “generation ship” is doing, how many people are actually aboard, and how much cash we want to throw at it.

Just hanging around our solar system in a graveyard orbit with a fairly small generational crew? Probably doable with current tech if money was no object. You don’t even have to do much recycling if you don’t care about the cost. A human only needs 700-800kg of oxygen per year. Water can be recycled, but a human “only” needs 30,000 gallons for a lifetime. That’s 250,000 pounds of water… but you could launch that with a single ares V. Food is a challenge (between 70,000 and 80,000 pounds needed for a lifetime), but you can probably put enough raw nutrients up there to make an edible slurry drink that would stay viable for a few centuries… and you’d have plenty of light and water for hydroponic greenhouses for additional variety. Energy isn’t that hard, either. If we didn’t care about the obvious safety risk, we could launch enough nuclear fuel to run a ship for centuries using current tech, with plenty of spare reactors and fuel shot up there just in case. Use the water in the hull as rad shielding and micro meteorite protection (ice makes a decent shell that can be “repaired” with a little heat and a squirt gun). Build a nice sized space station for everyone to live in, put plenty of spare parts up there, and you’re golden.

You can reduce those needs significantly if you do even a bit of work trying to recycle and reuse water/air and focus on things like lab grown foods and growing spaces.

None of that is impossible with current tech. You could lob enough food, air, and water to keep a small crew alive for generations… if you wanted to… and had an insane amount of money to spend.

Going to another star? Forget about it.

Happens to all of us. This is a deeply human experience :).

And it’s an experience we must have… because it comes at the cusp of every serious romantic relationship that you will ever have. We must make the leap of faith because it’s the only way to get to the other side of friendship.

If you never take the leap, you will never know. Knowing can hurt, but hanging on wishing hurts even more. Eventually they’ll meet someone else and it’s going to feel awful, and when you break down, they’ll tell you they wish you’d said something sooner.

That’s not to say being friends is bad, if a friend is what you want… but if you find yourself wishing for more, try. Buy the ticket. Take the ride. Worst case, you know the feeling isn’t mutual and you’ll be able to move forward in finding someone who cares as much as you do.

Will that ruin a friendship? Maybe. Is the potential to live your dreams worth it? Of course. Maybe you’ll get everything you hoped for.

And if it doesn’t work out… it’s okay to cry. It’s okay to be angry, sad, and hurt. Those are the moments that make the blue sky shine just a little brighter the next time you see it. You will find someone who cares about you just as much, but you will only find that person if you’re looking for them.
