Neural Imprinting: Ubiquitous, although it’s called “gnostic overlay” and “mnemonesis”. And while it is the standard educational technique (starting prenatally, with the axiom feed), it’s only the first step. After all, being able to download huge chunks of skillset into a chap’s brain is easy; successful integration and synthesis to make said skills your own is hard, and then practice, practice, practice!
Of course, in terms of pure fact-memory, being able to recall just about anything known by remembering it certainly helps. Assuming you have the intelligence and intellectual skills to do anything with the data, which is the hard part there.
Brown Note: Basilisk fractals, and their audible, etc., equivalents, which is to say, various forms of sensory input that can take advantage of cognitive bugs to actually crash your mind – and, at least theoretically, can implant thought-virus programming, although that capability’s never yet been seen in the wild. Most modern (artificial or modified) cognitive architectures include protection against known basilisk hacks, but known is, regrettably, often less than all. And baselines are still vulnerable, as are people who don’t keep up to date with Cognitive Threats Monthly. Apply your service packs, kids!
Doing it with a thought-virus that is implanted into the mind using regular educational axiom feeds or other mind-editing tech is too trivial to even mention.
