Because it’s uncomfortable to see decades of work copied so trivially.

But that's the thing, without the decades of work, it wouldn't BE trivial.

Everyone is standing on the shoulders of those which came before. If LLMs allow us to combine the incredible decades of effort and knowledge and experiences that's gone into building something as great as Postgres, and take that and combine the experience and philosophy that has led to the creation of a language that potentially provides tangible benefits, and for far less human time and effort that it would have otherwise taken...surely something that should be celebrated as absolutely incredible?

But who is getting celebrated? The people who spent a lot of time on the original thing, or the AI rewrite that everyone now uses?

The people benefit from all human knowledge, future human beings.

if only we lived in such a world

I mean, all of it? Maybe someone born post rewrite will think wow AI made a cool thing but nobody is going whoa Postgres is made purely by AI?

I can trivially copy any code even without an LLM though with a simple tool called rsync!

They have the source right in front of them.

Imagine the feelings of a dude who used to code in assembly and then some punk writes in c++ and uses gcc... decades of work wasted.

That is a completely different thing than LLM generated code.

They typically respect software licenses and thus comply with the original software's wishes.

LLM companies steal the original work and LLM users dont even know where the replicated code was lifted from or how it was licensed.
