I guess what @StanMan is referring to is solving using entirely CFOP blindfolded. It is not just eidetic memory but more about the interaction of your move & outcome, so, not impossible but it will take much longer. I know there are several folks who did entirely using CFOP but times were more than 10 minutes, I believe (somebody can correct me).It's been done, but it's much harder. The basic beginner's "OP" method just uses PLL algorithms with setup moves, and it's really not that hard to learn. M2 is worth learning for edges, though.
I've used to post here a lot about BLD progress but as @pglewis said, becoming more active in FB group.
