FWIW I think it captures the sentiment many users have towards software today fairly accurately, and every software engineer who has even a modicum of pride in their trade really ought to pay attention.

One thing I'd like to point out, though, is that this kind of stuff isn't really about micro-optimizations. Most software in the "good old days" wasn't really micro-optimized either. No, what this is about is bloat. Layers upon layers of abstractions that, in most cases, amount to rearranging the pieces in the way the author deemed most aesthetically pleasing. When I look at call stacks while debugging most modern software, I can't help but feel that it spends most of its time calling functions that call functions etc, 20-30 levels deep. Most data flow isn't from component to component, but within the component between those layers. And it all adds up.
