And even if "me learning something" means different neural rewirings than "you learning something" and isn't transferable, you could instead have 100 instances of yourself go and learn 100 different things, then combine all the rewirings at the end. There might be "merge conflicts", but I suspect it would still mostly work—and you could parallelize the work of finding ways to fix the conflicts! Even if none of that worked, at the very least you could have your branch-instances discover by experiment the fastest way for you personally to learn each thing, then have your main instance follow an optimal educational program, which I will arbitrarily proclaim to be 4x faster than normal learning.
