It doesn't replace programming, it _is_ programming. It's useful because it makes programming more accessible and in some cases the visual representation has benefits over text.
I see more and more professional fields and application interfaces adopting things like SQL, Python, Notebooks (Jupyter etc.), JavaScript etc. Excel is obviously huge. A ton of technicians that work with physical stuff are also writing code in embedded interfaces or on large screens even. Programming is not a thing only software developers do.
Think of it this way, even if it were possible to run an enterprise through lowcode tools, an enterprise would still hire an agency or consulting firm to build it, and so the decision of what tools to use still goes to the specialists.
