> I have hard time believing that you can learn quicker playing chess against AI.
I’d be more inclined to agree if everyone learned the same way, but we don’t. What works for you may not work as well for others.
For me and music, for example, I learn best by hearing and playing by ear. If I want to learn a song, it’s usually a good bit of time with me playing and rewinding, pausing, playing, pausing, rewinding, etc. I can read sheet music, but the process is woefully slow and not fun for my brain. I could watch someone teach me each part, but that also sounds boring, and I feel I learn better through my own method of trial and error because my brain has to work out the nuances - “was that a hammer-on? Was there a slide transition there? That sounds like a permutation of an earlier chord instead of a direct reuse of it! Etc”
Being able to play against AI may be just as valuable for person A to learn as playing against a human would be for person B. To suggest one is strictly superior to the other, in all cases, is very black and white thinking that doesn’t fit how people work.
