No arguments there! A huge majority of applications can afford to be written this way, even ones where performance is a concern (WhatApp, for example).

This is sometimes true for any one given app but it's not a good overall outcome.

It is why we have today multi-GHz CPUs with lots of cores and dozens of GB of RAM and yet... most actions feel less responsive today than in 1995 with a 120MHz CPU, 1 core and 1MB.

My comment was in response to the need to squeeze out every last bit of performance you possibly can. You're talking about ignoring performance altogether which is not what I'm talking about.
