many people would say: don’t put knives in the dishwasher at all.
Meaning, good kitchen knives...tableware is fine. But kitchen knives (slicers, dicers, etc) depend on very thin foils at the blade edge. The chemicals and heat involved in dishwashers can damage the blade.
(this is only marginally resolved by using serrated knives...those may not be damaged by dishwashers as much, but I have yet to find one that works as well as a pretty good kitchen knife that is even marginally maintained)
But curiosity can also be like R&D, and the funding of basic research, which can have huge payoffs that are unexpected compared to what they were originally targeted for.
Curiosity should at times be targeted, but if you are too targeted you can miss a lot of stuff, for example: how things work. Not “a thing”. But “things”, in general. In order to be good at life you need to know a wide variety of things, in order to be able to generate your own overall fabric of how the world works.
Also, being too targeted makes you boring.
