Not a word about the security implications?

The easiest reply would be "They are called books", or whatever container and format for information - and already there issues and risks are more than just possible, mitigated by filters one is trained to develop. The more acquisition of information takes the aspect of an "injection", a whole world of issues open.

From "I read War and Peace in one hour: it was about Russia", to all kind of mental poison (from "bad" notions to concretions of intellectual inadequacies): information has to be digested - processed and integrated.

So, on the point of view of feasibility: if knowledge implies diffused transformations (as opposed e.g. to installing an independent informatic file, non-integrated with its peers), that idea of injecting knowledge is absurd - it does not work that way. When you come to know that Paris is in that location, in that position on the map, you modify a number of notions: some directly related to Paris, others of all related entities - of the idea of France and its layout, of Montparnasse, of the Second World War, of the treaties there signed etc. Information needs to be digested to be productive.

I would think security wise it would be like medication. Everything from highly trusted,tested and expensive sources to the free for all of the black market.

I would suspect you are right though that the idea of a knowledge injection is absurd.

If an athlete takes steroids they are injecting strength in one sense but not like a movie that they take the injection and are superman 5 minutes later. Surely, there are biological processes that can't be sped up all that much unless we are talking about complete science fiction with total mastery of biology.

Except you can't do mind control by intercepting someone's steroid supply.
