No one is saying emacs is perfect, this is such an odd comment. Just because it is made as a real tool, as opposed to a product or something to sell more of, doesn't make it perfect. Table saws are meant to use in productive behaviour too and the fact that people cut their fingers off doesn't make them less of a real tool.
Not a great analogy. Table saws try to prevent you from cutting your finger with flesh-detection saw stops.
Wouldn't hurt emacs to change the default keymap, just like it didn't hurt table saw manufacturers like SawStop or Bosch to include safety mechanisms, it helps.
