true, but
1) Average Joe thinks ChatGPT actual understands what you say and what it outputs. Joe doesn't know it is just a probabilistic parrot, it actually thinks there is an "Intelligence" that generates new, original content based on actual reasoning.
2) you assume that the LLM is trained ethically, so that whatever biasis is will develop wasn't planned beforehand. What I said instead is that an ethical point I didn't consider is that a bad actor could plant those biasis by choice to promote its own agenda.
