It is frustrating how relevant philosophy of mind becomes in figuring all of this out. I’m more of an engineer at heart and i’d love to say, let’s just build it if we can. But I can see how important that question “what is thinking?” Is becoming.

Slow down… they may deserve the basic rights of living beings, not living intelligent beings.
Lizards have brains too, but these are not more intelligent than lizards.
You would try not to step on a lizard if you saw it on the ground, but you wouldn’t think oh, maybe the lizard owns this land, I hope I don’t get sued for trespassing.
Well, I used to have an area of expertise… Then we adopted a kid.
Kids are hard. Kids who had years of neglect and trauma… can be a lot harder. I love him very much, but he takes up so much of my time and energy, I just don’t have any time for my own stuff any more.
Also, my field (IT) has gotten weird as computers have gotten weird. Nobody uses computers any more, they use “devices”. And these devices all suck. They’re hard (or impossible) to actually back up, you can’t deploy software to them in an organized way, they’re a security nightmare, and the interface just isn’t as easy to use as a freaking mouse and keyboard.
And if you want to talk about actual computers, those suck more every year too. Oh the hardware is improving by the day, but the software hasn’t been cooperative in years. Always online operating systems, fake settings menus to keep the user away from the real settings menus… Actually, nevermind, I don’t even want to talk about OSs, they make me too angry.
And then there’s all the software packages that would rather be services than what they actually are, a product. Poor Adobe, just not filthy rich enough yet…
Anyway, it gets harder to do IT as computers get shittier, and I am falling behind, because I hate it.
This is hilarious, a win-win in my book. I get to laugh at the ridiculous claim about radio waves frying people’s brains or whatever, and at the same time, every day of stalling hurts an exploitive POS telecom company.
I’m rooting for the loonies! Protect our kids! You show those lizard people!
Well if there’s not enough sun, wind could be a better option. I don’t know much about the climate in slovenia, so either could make more sense.
As for these new kinds of batteries, I don’t have the hard numbers on hand, but I know the current installed capacity is really small. So as a product, they’re still really new.
Grid scale storage has come a long way. There are saltwater batteries and flow batteries in use now, those technologies are here, they’re just still being iterated on and improved. And as the renewables get increasingly affordable, the demand for storage will rise with it. Now we’re still mostly deploying expensive lithium batteries, but as more of that gets installed, the demand for cheaper storage will skyrocket.
So what’s the battery chemistry? Also, do they actually have an aircraft design, or is this just battery news?
That’s true, it does assume interstellar travel is physically possible, but at this point there are forms of interstellar travel that we know are possible.
Solar sails for instance, we know those work, we’ve tried it. Now if you wanted to travel to another star system with a solar sail, it’s just a matter of scaling that proven technology way up. We’re not ready to do that today, and we won’t be ready in the next 20 years, but to think that we wouldn’t be ready in 500 years, I find that idea far fetched.
But a much better technology would be fusion propulsion. With fusion drives you could get your cruising speed up to a meaningful fraction of the speed of light (perhaps 5-10%). At that rate you can make it to the closest stars in less than 100 years. And that technology is not at all far fetched. We truly are approaching working fusion power plants, it’s extremely likely that we can eventually develop fusion propulsion, or at the very least, fusion powered electrical propulsion (ion drive).
As for if it will ever be economically possible, I’m not at all worried about that. The fact is, there are a lot of resources and opportunities right here in our solar system, just waiting for people to utilize them. So people definitely will start mining and manufacturing in space eventually. And as we start to operate more in space, we will naturally continue to iterate and improve our methods of getting around. In short, over time it’s going to get cheaper and cheaper to make space ships and we’re going to get better and better at doing it. The economic factors are likely to fall into place eventually.
And finally, will interstellar travel ever be possible socially? Hey, your guess is as good as mine. I don’t think we have any way to answer that…
That’s definitely the right question! And honestly we don’t know, but it’s evident that we are first.
Given the age of the universe, statistically it should have already happened by now.
I’m not sure that’s true… I’m pretty sure that our sun is old for a main sequence yellow star in our galaxy. When you compare how long it takes for a star to get to the point ours is now, compared to the age of our galaxy, I believe it suggests that sol is part of a first wave of stars of its type. So if life really requires a star like this one to start up, then intelligent life starting just now could be right on time.
Now why is our start perfect for life? Again, we don’t know, but evidently it is. Sadly we only have this one data point, this is the only star where we know there’s life. So assuming that something about our type of star is perfect is about as sensible as assuming that life could start around any star. Is it that other kinds of stars produce too much radiation in the Goldilocks zone? Or is it that other kinds of stars are too variable in the amount of heat they produce? Or that other kinds of stars don’t tend to have rocky planets? We don’t know, but something about main sequence yellow stars could be special, and we have one of the first of those in this galaxy.
So declaring “we’re the first” requires some assumptions, but they aren’t crazy assumptions, and a lack of evidence of other older civilizations makes those assumptions stronger.
And to your point, the universe is much older than this it star, so I suspect intelligent life has developed many times before us, at least in older galaxies. But sadly I don’t expect us to ever meet life from another galaxy. While I think stars within a galaxy are close enough for travel between them, galaxies are very, very far apart. I don’t think life has much chance of traveling to other galaxies, at least not without some method of ftl travel (which I am also not optimistic about).
The whole ship either has to have enough energy to last potentially 100000 years.
Well, that depends on how far you’re going. If you pick a nice close target, let’s say 3 light years away, you can potentially get there pretty quickly. With fusion propulsion systems you could make the trip is something like 70 years, coasting most of the way. I’d need to check the math to get exact numbers, but I recall fusion allowing for pretty reasonable trip times.
But if you can survive for hundreds or thousands of years, then solar sails become an option. Then it becomes a materials science problem of how thin can you make a sail that will still hold together. The greater the sail to payload ratio, the faster you go.
Or synthetic life. (Robots)
Not really. Galaxies are pretty stable, stars orbit around the central black hole in the galaxy. You can absolutely travel between stars in the same galaxy, even if it takes a thousand years.
I don’t think there is a great filter. I think there’s an easy solution to the fermi paradox that doesn’t require great filters:
Here’s my hypothesis, intelligent species that manage to develop space travel do tend to expand out into their galaxy. When they achieve this level of technology they can settle most all of their galaxy in a matter of 10,000 years or so. That time period is very brief on an evolutionary scale. It’s estimated that life began on earth 3.7 billion years ago. That means it took about 3.7 billion years for earth to produce intelligent life, and then from that point it would take a mere 10,000 years to reach modern day, and 10,000 more years to settle the whole galaxy. That expansion happens so quickly compared to how long it took the planet to develop intelligent life, that the chance of two civilizations rising at the same time becomes very small.
It all boils down to this: there are no intelligent aliens out there in our galaxy, because we are the first intelligent species in our galaxy. We know we’re the first because if we were second, then aliens would already have settled this star system.
Probably there are lots of alien civilizations out there in the universe, but they’re in different galaxies.
Um, I think you’re mistaking species with kingdom.
“Birds” are not a species, “mammals” are not a species. I don’t think viruses are even described in terms of species because they don’t reproduce sexually. I think you’ll find that when you actually consider species, most of my points hold.
Various species have methods of communicating, from bees dancing to each other to whales having distinct regional dialects. Yes, humans have added some complexity to it by introducing technology, but that’s realy what it comes down to. Technology.
Yes, many species have some rudimentary way of communicating some kinds of information. But obviously bee dances don’t compare to any human language, of which there are literally hundreds. A bee for instance has no way to express appreciation or derision for the English language. My whole point here was that humans, on hundreds of distinct occasions, developed languages capable of conveying complex ideas. No other species has developed a language half as capable as any of ours.
Rather than picking the rest of that post apart, I’m just going to stop here. It’s pretty self evident that humans are impressive as hell. Denying that is… pretty dumb, and purely rhetorical.
As a side note, don’t get too excited about fusion, it’s largely a dead end. I expect it will only be really useful in niche applications (like spacecraft). It will be far more expensive than nuclear fision and not really offer any benefits besides abundance of fuel. There’s still a huge radioactive waste problem. On the other hand, the sun provides all the energy we’ll ever need, and we’re getting better at collecting it. I’m really not concerned about increasing energy demands.
How many predators can take down prey 50 times their size? How many species can thrive in tundra, jungles, plains, forests, mountains and deserts? How many species can be found on every continent? How many species figured out how to fly despite never developing wings? How many species developed hundreds of distinct methods of communication? How many species have been to the moon?
Humans are fucking badass…
Very well said sir. I think you make your point quite effectively!
I totally agree. I know a teacher who who likes to say:
“I believe there really is no such thing as a dumb question. As long as it’s an honest question (not rhetorical or sarcastic), then it’s a genuine request for more information. So even if it’s coming from a place of extreme ignorance, asking a question is an attempt to learn something, and the effort should be applauded.”

Oh, you can finish it up pretty quickly when you decide to. Just make a b-line for where all the big dungeons obviously are. You don’t need much for gear.
That’s not really the concern, quantum cryptography already works, we have more robust encryption techniques.
The problem is that the planet has a whole lot of saved communications still encrypted with old techniques, and those are all at risk of being decrypted later. If you were transmitting encrypted data, knowing that there’s was a man in the middle, you probably felt pretty clever, as even the watchers couldn’t read it… But they could record it and save it. Now all those saved recordings are likely to come out.
