Erlang's creator Joe Armstrong once said it like this (quoting from memory) "There's a moment when you go from not getting it to getting it, and you have about 24 hours when you remember both before and after, and that's when you have to write things down. After that you won't remember how it was not getting it"

Thanks for sharing this with me. I didn't know this was a widely known phenomenon. I'll take a look at the link to help avoid having these blind spots myself, thanks again!

I’ve heard it called and prefer to call it the curse of knowledge
