You are using a different definition of readable than most people are. Most people are using it to mean "the target audience can read and understand the code, and do so in a way/context that allows them work with it". Your definition seems to be "can read the symbols on the screen".

I can read Assembly. I can, in some cases, figure out what that Assembly is doing. I can not, however, work productively with it. I can read Assembly but would not consider it readable.
