I’m kind of late to the game on this, but I think the idea is so great with automation threatening a lot of jobs in the future. I recently came across this video with Quincy Larson on of the founders of Free Code Camp. This is a talk about JAMstack, but has a good explanation of how their courses are open source.
I’m self taught and this really would have been useful back in the day. There’s a part of me that loves to take tests, so I’m gonna try to complete as many of their courses as I can in 2019 starting from the perspective of a beginner. Check them out, I’d bet there’s something there for everyone.
