Your argument is "they're designed to influence us" right?

Amazon reviews are paid influence. Reddit posts are paid influence. Everything everywhere you read online is paid influence. I'd rank LLMs between "people I personally trust" and "random people online."

I trust them as much as any other online source, which is to say, sort of, but only as a starting point for research.

Do you have a better alternative?

Even if they're (somehow) bias-free, you're still stuck with "the state of the internet circa 20XX" from the training data.
