Alva Noe: Don't Worry About the Singularity, We Can't Even Copy an Amoeba

Goaway Re:AI researcher here (447 comments)

Intelligence, as a very baseline requirements, should be adaptable.

Pretty much every single AI implementation is designed specifically for a given task. It can not adapt itself, without outside help, to a problem outside its initial scope.

That is not intelligence.

Ask Slashdot: Is Non-USB Flash Direct From China Safe?

Goaway Re:Not a security risk, but a fake risk (178 comments)

It's not that the flash is low grade, it's that it just plain doesn't exist, and the card will just discard data after a while. What flash there is in there probably works, but is useless.

Ask Slashdot: Is Non-USB Flash Direct From China Safe?

Goaway Re:I'd be more worried... (178 comments)

The price is the dead giveaway that it is a fake. Flash memory does cost money, and it is sold at minimal margins. One fifth of the price means less than one fifth of the memory, every time.

The card will pretend to be as big as they claim, and it will silently just lose your data.

The difference in gravity is negligible. The lack of drag does help, but you don't need to go quite that high for that. At 7 miles you're past most of the atmosphere already.

"Microgravity" is irrelevant in this context, it just means the ship is falling. Sure, it's a little bit easier from 68 miles than from 7 miles, but again, that's just the altitude, which is already the easier part. It does nothing to help you gain orbital velocity.

And, rocket engines have not developed that much in 30 years. We are still stuck with the weight-to-energy limitations of chemical reactions.

"Suborbital" is a very different concept from "low earth orbit".

"Suborbital" means you don't have enough speed to stay in orbit. Getting to the required altitude is the easy part of getting into orbit. Once you're there you need to stay there, which takes far more energy to achieve.

SpaceShipTwo is strictly suborbital, as is apparently ASM-135.

Goaway Re:Who fucking wrote this? (594 comments)

Sending up balloons very, very rarely causes people to die, you know. That was kind of the issue here. That what SC2 is doing is not worth dying for, not that it's not worthwhile at all.

Sure, there are some niche scientific uses for suborbital flights. But that is still isn't the same as managing orbital flight.

The ASM-135 was also suborbital, you'll note.

No, what I am saying is that if the Wright brothers started today, nobody would think they were doing useful work.

No, being a kinetic weapon it would gain a lot of destructive power by not being in a nearby orbit. The satellite would slam into it at orbital speed.

That would all make sense if we didn't already know how to get into space.

I don't know if you've notice, but we do. We don't need to take baby steps to get there, we can already go. This isn't a scheme to figure out how to get into space, it's a thrill ride for rich people.

The people who are actually trying to get into space aren't doing anything like this. They are building things that actually go into space.

That's going to take a seriously huge ship, which will be very different from the SpaceShipTwo, not to mention the gigantic plane to carry both of them up.

If you want to discuss things, learn how to behave in polite conversation. I have zero interest in ever talking to you again now.

More energy, yes. And more energy means more fuel. More fuel means more mass. More mass means even more energy. And so on. To scale up to the point where you can actually reach orbit will require a vastly different design, far bigger and heavier. And at that point, what you learned from the SpaceShipTwo no longer really applies much.

We sure have better space travel than the SpaceShipTwo could ever provide, though.

Like the other guy says, reaching orbit is hard. We're not going to suddenly have a miraculous development that gives us super-powerful engines that makes it possible for something like the SpaceShipTwo to reach it. And if we did, anything the SpaceShipTwo had learned would pale into utter insignificance compared to the massive possibilities of that miracle engine.
