That's a terrible take. Programming is often a rarer and more difficult skill to hire for them many of the domains programming jobs touch. Most places will hire you just based on programming knowledge, and will train you in the domain knowledge.
All of the jobs you've listed are highly technical fields, and unusually specialized among programming jobs. A general SWE position doesn't often require much more than just programming.
I have not been able to find a place like that, most have a long list of requirements. Can you suggest any?
The problem is, the employer is probably wrong (they did not do the correct requirement analysis on this), and actually don't want a "just a Programmer", they want a "Requirement Analyst"/"Functional Analyst"/"Design Analyst", and those are the rarer and more difficult skill to develop and find at all.
Based on my observations, biased due to my specific niche, most people who program just ... well ... shouldn't. If there were doctors practicing medicine as bad as some people who call themselves programmers program, then we'd have riots!
Really curious, what counts as "programming knowledge"?
