It's pretty likely that I've done the same thing. I mean, I've written enough CRUD functions in my life, for example, that in all likelihood I'm regurgitating stuff that's a copy, for all practical purposes, of stuff I've done before as work-for-hire for my employer. I'm not stealing intentionally or consciously, but it seems quite likely that it's happening. And that's probably true for many of you, at least that have been in the industry for a while.
I asked agent X what is the source of training data it generated code from, it couldn’t say. Then I asked why the code implementation is exactly the same as the output of agent Y. It said they were trained on the same ‘high-quality library’, and still couldn’t say which one.
So I guess that’s fine because everyone is doing it.

When I write fizzbuzz do I owe royalties to the inventor of fizzbuzz? Is my brain copyright thieving because I can write out the song lyrics from memory?
