I actually imagine it's the opposite of what you say here. I think technically inclined "IT business partners" will be able of creating applications entirely without software engineers... Because I see that happen every day in the world of green energy. The issues come later, when things have to be maintained, scale or become efficient. This is where the software engineering comes in, because it actually matters if you used a list or a generator in your Python app when it iterates over millions of items and not just a few hundreds.
