What's there to advance to?
Without a revolutionary new platform to build apps on that no one has ever developed for before, there is basically no reason to believe there is any software left that has some business or economic value that hasn't already been written.
This is probably true in the consumer facing software space. But in business, industry, and academia, often there are novel data generated by some new or refined process. And this needs new software that correctly handles both the nature of these new data and meet the goals the data is collected to advance. This sort of software is also usually poorly represented in training sets, if represented at all.
this implies that the only thing that can change what needs doing are technology platforms, which about 6000 years of human civilization would indicate is not the case.
that you don't see this as inevitable worries me dearly
