So... I've been thinking (again, I know, ask me and I'll stop), and I had a question. This most likely got discussed into the ground somewhere early in the story, so, if it was, please feel free to just point me in the direction of that discussion.
We know that there are one-off hyper advanced pieces of technology lying and walking around. They are marvels of engineering, especially given the tools that were used to make them. But what about more fundamental sciences? Theoretical stuff, maths, that kind of thing. If OL was to go to
Scopus-16 and search for "bleed physics", would he find anything not related to medicine or criminology? Maybe not in high impact journals, but at least in some publications on "alternative" physics? I mean, we know that Sivana senior published some stuff in his earlier days, even if he later deleted his stuff from the web. He might not have been a unique case in the practice of actually publishing his findings.
Speaking of science and mainstream research. From existence of STAR labs and the fact that Captain Cold (I think it was) was invited to give lectures in a university at OL's initiative, we can infer that at least some hyper-advanced science (as opposed to engineering, which is, in this context, a practical implementation of science if the form of technological devices) spreads through the entire scientific community. And this should affect research in some interesting ways. I mean, ITER and other fusion related big projects are probably not a thing (and if they are, OL should pay them a visit and kill all funding, because fusion is going to be made obsolete by bleed tech before it's even accomplished), and fundamental science is better funded in general.
And on the related issue. League doesn't share advanced technology with the world for a number of reasons. Weapons non-proliferation is one. Preventing a fostering of dependency on the League members is another. Kinda like USA won't consider building a modern nuclear power plant in Cambodia. On the other hand, knowledge is knowledge and it's knowledge everywhere. Thousands of people all over the world are working in the field of pure math. I am fairly sure that Kryptonian database, and quite possibly OL's knowledge databases have math knowledge centuries more advanced than Earth. Why not release that? Theoretical physics textbooks from Thanagar or Krypton (Kal-El should have college level textbooks archived somewhere). Because, you know, while you wouldn't want a nuclear plant built in Cambodia, denying a gifted Cambodian student from studying nuclear physics in USA (if they can pass exams with flying colors) would be rather callous.
In fact... Why hasn't this idea been floated? Get an agreement with, say, Thanagar. Send a group of students to study STEM subjects at their university, and receive some of their students to study thaumaturgy in Atlantis - one field where Earth seems to be quite advanced is magic, from the looks of it.
Yes, sure, payoff will be less immediate, but it will directly help thousands of people and help humanity as a whole to become more advanced. Hell, Kadabra is teaching school-level classes in jail. Even if he only had an equivalent of high-school education from his time (and he likely has at least bachelor's levels of education), he should be doing lectures for the best and brightest of the world over the video conference (and later getting a pardon for his great contribution). Same with Truggs, really, and the fact that he didn't bring a full upload of scientific literature shows that he's a supervillain and, thus, an idiot.
