I don't think it necessarily bears repeating the plethora of ways in which LMs get stuff wrong, esp. considering the context of this conversation. It's vast.
As things develop, I expect that LMs will become more like the current zeitgeist as the effects that have influenced news and other media make their way into the models. They'll get better at smoothing in some areas (mostly technical or dry domains that aren't juicy targets) and worse in others (I expect to see more biased training and more hardcore censorship/steering in future).
Although, recursive reinforcement (LMs training on LM output) might undo any of the smoothing we see. It's really hard to tell - these systems are complex and very highly interconnected with many other complex systems.
