I think it applies to an extreme degree in programming - but probably in eng. & STEM fields generally as well. Something about having to care a lot about very small details, and especially when the big picture is not something you particularly care about. But yeah, I don't have any experience in other fields so maybe it's not that unique - I guess it was driven mostly by the experiences I've had with people not getting it, and being frustrated with me that I wouldn't "just work a well-paid coding job for 5 years".
