Ask HN: Software jobs with high barriers of entry?

Are there any software jobs that actually have a high barrier of entry? Besides maybe an LLM Engineer?

I feel like no matter what type of engineer you become there is always gonna be a bunch of ppl who you’re competing with. Perhaps someone are slightly more competitive than others like a devops person, but overall, i feel like the entire SWE field has become a commodity

Are there actually any software jobs that require a ton of schooling, or a ton of self education? Like literally years and years like you need to become a pediatrician or a lawyer
