Why programming manuals aren't on audiobook

This actually made me angry. The "humor" is based on pointing out the denseness of programming instruction in audio format, as if to say, "This is so hard, who would be stupid enough to think that this is a good idea?!?"

I have a blind friend who is a programmer who LISTENS to source code in order to program. We are both in the same Computer Science PhD program at a well known US University.

This video insinuates that programming is so complex that only "normal" people can do it, and that is offensive.

And, for the record, I do not use Swift, but I could understand exactly what was being described. This video is insulting.
