Although it's in a different area, I wanted to mention https://calmcode.io/ as an excellent example of a calm learning platform.
There is a whole movement around enshittification, and I see potential in this kind of app, even though it still seems to be a niche.
Oh, thanks for this link. Looks great and it may suit me well. I need to settle in and learn Python but I am experiencing tremendously severe dysregulation at the moment, and my normal quick deep learning is simply not happening.
