>Look, most modern software is spending 99.9% of the time waiting for user input, and 0.1% of the time actually calculating something. All that says is you should focus your energy on the increasing the value of .1%. It's not actually an argument to not spend any energy. It's like saying 'Astronauts only spend .1% of their time in space' or 'tomatoes only spend .1% of their existence being eaten' - that .1% is the whole point. You can debate how best to maximize that value, more features or more performance. The OP is suggesting folks are just leaving performance on the floor and then making vacuous arguments to excuse it.
