That's true for internet searching. How many times have you gone to SO, seen a confident answer, tried it, and it failed to do what you needed?

Then you write a comment, maybe even figure out the correct solution and fix the answer. If you're lucky, somebody already did. Everybody wins.

That's what LLMs take away. Nothing is given back to the community, nothing is added to shared knowledge, no differing opinions are exchanged. It just steals other people's work from a time when work was still shared and discussed, removes any indication of its source, claims it's a new thing, and gives you no way to contribute back, or even discuss it and maybe get confronted with different opinions of even discovering a better way.

Let's not forget that one of the main reasons why LLMs are useful for coding in the first place, is that they scraped SO from the time where people still used it.
