Main idea computer programmer passage

For this passage , I identified the main idea as
“Computers are dumb”

Is it correct?

Not really…computers are unbiased and they will do whatever they are told to do…single-minded, literal-minded and simple-minded (“three related adjectives”) all mean that it will not analyze how difficult or easy the task is but instead will solve it. It itself, doesn’t have an opinion on the task given to it. This is in a way similar to theoretical mathematics…so does it mean theoretical mathematicians are dumb??..They are the ones postulating most of the different laws governing mathematics.
