We have a very good science discussion thread over here, but we've never had a thread just about technology. So I'm just going to start one.

I'm hoping that here people can discuss all things tech, from the history and impact on human society, to new advancements, to just general thoughts and questions that you might have.

I'll get it started by posting this very interesting article on the history and development of stealth technology that led to the F-117 Stealth Fighter. The program was originally code named "Have Blue".

Worth reading if you like this kind of stuff:

So, what ya people think about the F-35? Been hearing it's op as hell, but way too expensive and with lots of design issues. Think it's worth it?

For those interested in the history of the Space Race, what happened to the Soviet Space Shuttle (the Buran) is a very interesting and sad story. What remains of those shuttles are left to decay and eventually ceases to exist (one shuttle was destroyed by a roof collapsing on it). The images and video of these shuttles are amazing.

I think that designing a single air frame that can then be adapted to so many different roles is fundamentally a flawed idea. And that program has had nothing but problems since it started, and cost more than a trillion dollars. It's one of those programs that makes sense in theory (given certain assumptions), but in practice it's hard to make it work. You end up making too many compromises.

I think it's ultimately worth it, when it's done. But considering how long it's been in development, it kinda amazes me we've even had fighter jets for as long as we have.

That said, my country has just signed a bill thats going to replace our aging F-16's with the current F-35's... and I kinda get the impression the deciding factor was that the F-35 is American and my government is hoping for American investment, rather than taking the operational and seemingly better equipped F-18 or the local produced Eurofighter Typhoon, which also seems to be better equipped and is also in operation.

Is Elon Musk right about AI? Should we be extremely cautious, yes or no? Seeing how AI behaves in different tests, I would be very concerned if they were to get smarter and have more control in our technology. I don't know exactly how true it is but I heard Bitcoin was created by AI, guess you could chalk it up to conspiracy Theories, but it seems to have some truth to it.

Yes we should be concerned, but an AI that's comparable to a human brain is still along ways off. But, eventually there will be super-intelligence AIs and at that point we should be very worried.

I heard the creator of the bitcoin was very secretive and when the best hacker tried to hack it they couldn't because the system pretended to be hacked, but then complete changed, making it completely unhackable. Very weird if you ask me.

I'm not sure what you're talking about. Bitcoin was created by a human, and there's nothing mysterious about it. There's a whole lot of crypto-currencies like that around now. The only "mysterious" thing about Bitcoin is why people are gambling so much money on it. A lot of people are going to lose a lot of money when the price inevitably crashes.

@willpayton: Nothing special about it, they created a new language of some sorts. I wouldn't be surprised if other AI's do the same. And have you heard of that one AI that always tries to escape when turned on? Very weird behaviors.

I heard the Bitcoin creator was very mysterious, like no one knows exactly who he is or where he is. Yeah his name is know, but not really much else. I believe an AI created it, don't AI's run part of it too? At the very least I think there is evidence that AI's run the security systems. The most renown hacker couldn't break into it.

A lot of people think it wont crash, I wouldn't invest in it.

Clear wood.

After the color is removed, polymers or epoxies can be injected to strengthen the wood. The result is stronger, transparent wood

If used as an alternative to glass windows, it would provide much better insulation. Thus reducing energy consumption.

Possibly a lighter, stronger alternative to steel. Could be used to create energy producing solar windows.

@willpayton: this is more AI focused, but what do you think of Ai named Sophia who is a Saudi resident actually talking about evolution in Ai and eventual family groupings. Do you think it was programmed to respond like that or how do you see said outcome if this is more of a complex reasoning among the robot. Future implications - you can bring up Skynet if you want but I was curious on your PoV regarding this

I'm not super familiar with it, but after looking up some video it's definitely programmed to say those things. It just looks like a "chat bot" type AI that goes through a decision tree based on the user input... in this case, whatever it thinks the person it's talking to said. This is still very far from an AI that can do real thinking.

@willpayton:

Buran was a better design than the shuttle IMO because the orbiter didn't have engines. All the power came from the rocket Energia and Energia had the highest thrust of any rocket ever built. So the rocket could be used in a swing role. It could have carried super heavy payloads to space with the Buran detached. Also because of no engines and fuel, Buran was safer for the cosmonauts. Too bad the Soviet union broke up and Buran-Energia was scrapped.

@willpayton:

I think you at right. A single airframe design for multiple roles is an inherently flawed Idea. The SVTOL take off capability is a great design for the F35 but look what it does to the payload capability. Also the design is Russian isn't it. From a Yakovlev jet. What are your thoughts on Su57

Yeah, I agree with that. However, it's important to note that the Shuttle had those engines because it was intended to be re-usable, and in theory having the main engines on the Shuttle as opposed to attached to the fuel tank meant that you could reuse those instead of throwing them away after every launch. Those engines are very complex and costly, after all. So the idea had merit, it just happens that a lot of the assumptions about the re-usability of the Shuttle and launch costs ended up being wrong.

Yeah. That's the case. The assumptions about the shuttle's reusability were all over the top. Even the technology of the ablative tiles were not matured then. What are your thoughts on Orion or Dragon V2. Do you prefer a shuttle like spaceplane? Almost all the new or in development reusable spacecraft have all abandoned the spaceplane idea except the US's Dreamchaser and the Indian RLV-TD/Avatar

The "space plane" idea makes sense in some very specific mission types, but for most it doesnt. So while the Shuttle was very cool and inspirational, it was almost guaranteed to be a failure in terms of cost no matter how well executed the ideas were. As far as the new vehicles like Orion, they're better designed and have access to much better tech than the Shuttle, so I think they'll do well. The main threat to the NASA projects, as always, will continue to be the lack of commitment and vision from the government leadership. Every President inevitably tries to sell a lot of stuff to the public that they dont understand and have no intention of making Congress pay for. So these programs keep coming and then going when they run out of funding and have to be cancelled or heavily modified.
