> in fact, many FIRE blogs are from non-eng people

I don't disagree with your overall point, but I don't think "number of FIRE bloggers who are engineers" is a good proxy for "number of FIRE people who are engineers".

Why do you say kids are incompatible with FIRE? They add some expense, but it is not insurmountable with a high income like many senior software engineers enjoy. There are prominent FIRE folks with kids -- e.g., "Mr. Money Mustache."

MMM sells shovels in a goldrush, and got divorced (with relatively young kids) out the blue while selling his white picket fence (albeit a cheap one) lifestyle dream for years. Hardly the one to bring up as an example for a successful FIREee.

I wouldn't go as far as say they're incompatible; I'm sure it's doable. But there's a pretty big difference in believability between the claim that "engineers are much more likely to be FIRE people, to the extent it makes a noticeable difference in the engineering job market, now of all times" vs "FIRE people w/ kids exist, but are outliers among outliers"

Ok, that seems reasonable. I got stuck on "there's plenty of engineers who have kids (hence, very much not FIRE)," which seems like an oversimplification of your views.
