Very interesting thoughts and ideas.

I have shaved with my eyes closed but that is a short time using a skill that I have had many years of experience with visual feedback as I understand you have. Starting from scratch would be much more involved.

I used the subtitles because I don't speak French but I would have understood many of your points using my vision instead of my hearing.

I could go on and on with this............

One of my favorite lessons that I learned in school and my wife used in here teaching at the second grade level was to write the instructions on how t make a peanut butter sandwich.

Pretty silly and fun but it makes you realize the importance of communication and how something so simple can be difficult.

Using SRP as an example also i think that trying to help and teach someone at a distance through the medium of the internet can create issues and problems that although minor get misunderstood.
