But, you know, if you saw something like, all your visible examples were like the strings

  123 456
  234567
  345 678

and the program replies with something like what you wrote: “Remove the middle character from any 7-character strings to make them 6 characters in length”, it would actually take a programmer’s mind to be able to envision why this might in some cases be wrong. Most people who are not programmers would, I think, see this as equivalent to “Remove interior spaces from each item”. I suspect that the skill required to choose an algorithm correctly is the exact same skill required to actually being a programmer.

All this then buys you is that you don’t have to remember the function names.
