Now, it can be argued that if North Korea didn't have any knowledge from outside about the existence of nuclear weapons that it would take their own scientists even longer to come up with that technology on their own. Maybe hundreds of years longer.

When the US developed the atomic bomb, I'm not sure the science of the device was even the rate limiting step. I'd lean more to figuring out how to separate Uranium 235, building the factories to do it, and then the inherent time it took to do the separations were rate limiting.

Even though developed countries now have the scientific infrastructure in place to better exploit advanced technology than we did 150 to 200 years ago, it might be questionable how many steps ahead we can jump.

Let's take the example of the microcomputer chip. If we had dropped a modern day laptop into the labs of Bell labs in 1950 (shortly after the invention of the transistor but 2 years before the patent of the first integrated circuit) how fast would it have sped things up? I think it would have been less than a factor of 2. In other words, I don't think that we would have had today's computers by 1983 if a lap top got dropped into Bell labs in 1950. There are too many advances needed in materials science, growing silicon crystals, material deposition, photolithography, wire bonding, doping, that would not be revealed by just being given a laptop. Those would have to be learned the old fashioned trial and error way.

If we speculate on alien technology, we can start by thinking of technology as the ability to manipulate matter, energy, and information. What if the device manipulated dark energy or dark matter? We don't know what these are. Similar to an 1820 automotive engineer may be puzzled by the substance gasoline with very limited analytical chemistry tools to figure it out and where it came from. Having the vision provided by the prototype can speed things up, but only by so much.
Excellent answer.

No way they could reverse engineer car before 1850.

You have to create the machines that create the machine tools to make the car.

Electronic components before you understand the electronic general practices? Not happening.

At the EAA airshow this weekend, I bought up the subject wondering if the Wright brothers, Martin, Curtis, and all the initial early 1910s aviation innovators could have imagined the F22.

If a Raptor went back to 1910; they could have not figured how to reverse engineer it...too much leap of technology. The jet engine and advanced materials was a HUGE game changer. Piston aircraft was made obsolete. Our WWII military technology was scrapped over the next 20 years.

If an NASA atomic powered satellite had fallen back in time to 1850, how many people would have died before they realized that the funny looking material was killing people? Or the energy conversion, filtering, and conducting circruity that was contained within?

Alien technology? If an vehicle appeared that was powered by anti gravity and control units were solid material not on our periodic table or polymer; would we know to take it apart?
