The problem is not this advice, but that people tend to stop reading (or remembering) there. It's misapplied or misunderstood so often that I wonder if it shouldn't be promulgated. Today something like this may be more appropriate:
"You should pay attention to performance, but your algorithms probably won't be the problem. It's more likely you're doing something stupid or wasteful, probably with the help of your technology stack."

That's EXACTLY my problem whenever I hear this or similar advice. It's exactly what I think when I hear people (mis)quote Knuth by mindlessly parroting the old adage (optimization is the root of all evil). Too many people interpret this as a licence to waste resources and bloat your program with reckless abandon to an egregious degree, that I too think people should probably not say spread stuff like this.
