Some of what you are claiming is false. Most chess AIs for example can identify almost every opening move in existence. Something no human can do. That's a type of position evaluation, and a good starting point for further research. No free coach is going to sit for 4 hours straight, 5 days a week, playing thousands of games exploring variations of a particular opening. That kind of self-study will definitely help you become a better player. Humans just aren't willing to be that opponent, especially to a beginner and not for free.
Also I'm not claiming you can learn quicker by exclusively using AI. I'm claiming you can learn quicker by adding it to your set of tools. Human coaches and books are other tools you can or should use.
Even the some of the best chess players in the world are now using AI opponents to explore new ideas.
Chess engines are very important for grandmasters, for sure. But for beginners they are mostly useless. That’s what I was arguing about.
Regarding openings - the best place to learn are books/studies/even Wikipedia articles that explain the ideas behind the major moves and variations, which chess engines don’t do. Also, a human can explain which opening are good to play at your skill level and which are not.
Regarding free coaches, playing with a friend/relative over the board and discussing the game afterwards has a similar effect.
Chess engines aren't useless for beginners. That's an empty claim and is as easily dismissed as it was made.
I gave a list of reasons why a chess engine is good for learning. Refute those as a start.
Here's another reason: an AI engine will point out illegal moves, and patiently over hundreds of games in your home. A free coach isn't going to come to your house and do that.
Neither will most friends or relatives. People get bored and move on.
