My main point is that when people think about "learning", they think about learning new pieces of information. Reps only reinforce old pieces, they don't teach anything new. Retaining knowledge is part of learning, sure, and I saw your article about "learning is remembering" which was a good read. And I support your initiative, spaced repetition is an amazing tool. But I'd still say "learn exponentially" implies more than just retention. I'd personally love a system that lets me pick up exponentially more new knowledge per day, though I'm not sure if that's possible
