Perhaps that is the real danger. Everyone except a small elite who (rightly) feel they understand how LLMs work would simply give up serious thinking and accept whatever "majority" opinion is in their little social media bubble. We wouldn't have the patience to really engage with genuinely different viewpoints any more.

I recall some Chinese language discussion about the experience of studying abroad in the Anglophone world in the early 20th century and the early 21st century. Paradoxically, even if you are a university student, it may now be harder to break out of the bubble and make friends with non-Chinese/East Asians than before. In the early 20th century, you'd probably be one of the few non-White students and had to break out of your comfort zone. Now if you are Chinese, there'd be people from a similar background virtually anywhere you study in the West, and it is almost unnatural to make a deliberate effort to break out of that.
