I have a hunch it is because many people, myself included, see a lot of software development getting replaced by generalized AI in the next 10 years.
(I disagree on the premise, BTW. I saw a number of successful machine-learning systems at Google, and the most successful were always the ones that combined machine-learned functions - sometimes many of them - with traditional algorithms. AI is a tool that extends the reach of software into new problem domains, it's not going to replace software itself.)
