I used to read FIRE books and blogs (one of my favorites was https://www.mrmoneymustache.com/), and participate in some of the online forums. Lots of interesting commentary, and especially Mr Money Mustache has some really great articles about controlling your own financial life, and not getting caught on the consumption treadmill.

I do think that most FIRE people have been blinded to the problems of the current monetary system by the fact that their main strategy (save money, invest in index funds) has been very successful over the past decades.

Also Mr Money Mustache wrote an article Why Bitcoin is Stupid, check it out for fun if you're interested

One thing that struck me starting maybe 5 years ago is...how the FIRE movement has started to be taken over by wokeness. I was unceremoniously kicked off a forum that I'd been a contributing member of for many years, for responding to an post about the vaccine with something along the lines of "maybe you should do some independent research before getting the shot". And that was that.

I read an interesting article recently, along the lines of "all organizations that are not actively anti-woke, will become woke". I think that's happened to an extent with FIRE as well.
