I was a kid during the Rubik’s cube craze of the 80’s. With the help from a book I got at the library I could solve it in about 20 minutes. I think I lost interest after I figured how easy it was to just take apart and put back together solved. Back in 2001 I got interested in the cube again and bought one to see if my adult brain would be better at it. I got my time down to under 2 minutes. It wasn’t as hard as I thought it would be. Just some pattern memorization. Under 2 minutes was good enough for me though, trying to get faster than that seemed more like math homework than something fun to do while waiting for the stoplight to turn green.
