a whole lot of stuff has been derived from ergot alkaloids. Albert Hoffmann alone found drugs to help women survive child birth before LSD stole the show.
Huge fan of SRS here. Anki never really gelled with me personally. I still use it but really prefer this app called StickyStudy. It’s mostly for learning Chinese / Japanese but there was a generic version which has sadly been abandoned by the dev. It has very straightforward SRS / leitner system and a bit more simplified ui. Not my app but just wanted to share and maybe inspire someone to make a successor ;-)
