No code/low code may increase demand for the software frameworks that empower the domain experts, but this does not mean it increases the demand for professional software developers.
Most of the successful deployments I've seen involved a lot of programmers regardless; either to advise the domain experts, or to customize the solution to the specific needs of the organization, be it with custom components, or interfaces to other systems. There's a lot of untapped demand for software solutions that'll keep programmers busy as total project costs fall due to increased automation.
