Honestly, the Pharo language and environment aren't hard to learn, except that the environment seems to change with every major version. Try the Pharo By Example book. There's also probably a YT video series. Actually I've considered making one myself, or at least doing an intro video to cover some hangups that people new to it have, but at this point I'm trying to focus on the things that will make me the most money before GPT and rest render me unemployable.
