I have more meaningful intellectual conversations with LLMs in a given day than in a month on social networks
Social media felt this way in the early days, too.
they almost never feed me misinformation (and never deliberately)
This is dangerously untrue. LLMs will deliberately tell you the things you want to hear. They even "call you out" in exactly the ways that are most palatable to you. There is ample evidence that LLMs can be biased. The ability to broadly influence individual opinions, without even needing bot accounts on social media is exactly one of the reasons so many people who want power/money are flocking to control these LLMs.
so many of my interactions are with jerks
This is one of the ways that the LLMs are "scarier" and more powerful than social networks. Real people are more likely to be obviously pushing agendas or otherwised easily dismissed.
LLMs are the ones getting better
Getting better at what? The things you list are exactly the things that make LLMS subtly powerful and far more dangerous that social media. It's the reach and anonymity of social media without needing to control a feed algorithm, deal with content or people that doesn't fit your agenda, or produce fake content that does.
