I'm reminded of rms's anecdote about secretarial staff learning to write Emacs macros at MIT because they didn't realise it was programming.
This suggests that current, important and well-meaning attempts to get non-programmers to meet code head-on as code may be misguided. Programming is generally easier if you're not thinking about how much it isn't something you do.
I don't believe that there is no such thing as a right brained person. I think this is a cultural myth. Same as, "you only use 10% of your brain's power". These, and similar, are false memes - iow hokum.
Precision is not the only important element in programming. There's a level of abstraction, such as found in the field of semiotics, that is highly important to the world of computer science.
