For sure. The older I get, the more I try to watch out for this effect. It's a pain, but one of the nice parts is that it drives you to look for deeper principles. E.g., when my dad started coding, machine time was really expensive as was storage space, so everybody optimized for those things. Hello, Y2K! Now the opposite is true: developer time has gotten more expensive, and computation is cheap. In one sense, that invalidates a lot of old expertise. But on the other, optimization is still usually important, we're just optimizing for different things. A little reframing of habits and you can end up with a more flexible and subtle model.
