Because we are human.

(As a human, it's more physically taxing to think, and less taxing to relax. Conserving internal resources improves our survival odds. So when an opportunity presents itself to use less effort and still gain out of that, we tend to take it.)

As human technologists, I believe we need to protect humanity more.

In everything that we do, we need to think about the ways that our proclivities as a species can be compromised by our development of technology.

It involves cognitive effort to set a good lowest acceptable price. We don't want that, we want to reduce this effort that's what the tools are for

That would require thinking, and thinking is the thing everybody seems to want to outsource to LLMs.

Because a lowest acceptable price probably depends on doing research and making a decision.
