It's already a fairly high skill profession in general. The seemingly-lower-skilled roles tend to be the ones with higher design/creative requirements on the programmers.

Agreed about the barrier to entry raising though, we're already seeing that in the glut of CS grads who can't actually get a programming job right now. Personally I suspect that this is a cultural issue more than an economic one, though. Companies need to alter their expectation about entry-level engineers and develop a culture of mentorship/apprenticeship so that advanced analysis, architectural, code review, and AI management skills are all passed down successfully.
