I think you've hit the nail on the head with the disdain. I have no real humanities education, did exclusively STEM/languages after the age of 16, but I learnt quickly at university and in my first job that STEM is nothing special, that all disciplines have something to contribute, and that ignoring them is just going to lead to ignorance on my part. If you study to do software engineering from the earliest age you can, do CS at university, don't join any clubs with others from non-STEM backgrounds, or even go to a STEM only university, then join a tech company big enough that you don't have to talk to non software engineers, you've just spent your life in a bubble. Sadly I think this is too easy to do.
