Understanding computing and programming is useful in careers that aren't specifically centrally about programming, in much the same way that being able to write is useful in careers other than professional writing. But, sure, more people programming will mean more people who are can take jobs that are centrally programming jobs, which is a good thing for everyone except incumbent workers in the field who have more competition.

It also means people working in other fields who can more efficiently applying computing to their own domain, either directly or by being better able to identify opportunities and work with people who are primary programmers.to realislze them. That's also a general win.
