That's pretty much the message that I took from it.

In Fahrenheit 451, the people decided to censor themselves and took pleasure in it. These days people have access to a ton of information, but choose to self-censor by engaging mostly with like-minded people forming echo chambers instead of debating differing viewpoints openly.

I agree it hasn't aged particularly well, but it still is relevant. However, I think the more likely distopia is that of Brave New World where we optimize ourselves out of our humanity and instead seek pleasure and order over progress and diversity. That being said, it still has a good message, for those who are willing to look at the themes and find how they might apply to us today.
