So many programmers saw "Premature optimization is the root of all evil" and thought it means "Caring about performance makes you a heretic".
You can't hotspot optimize a Fiat Multipla into an Formula 1 car. When every software you run creates a dozen factories to replace one for-loop, you get the modern desktop experience

This is very well said. Also, with enough experience, many good programmers will "know" where the hotspots will be, while writing the code. So, they can be "sloppy" in areas where it doesn't matter, and "care more about performance" in areas where it will likely matter much more.
