Stack stitching and AI as the future of software?

I've interviewed a Stanford professor and he gave great advice on how software engineers should view their careers.

One thing he mention is stack stitching – this is when you stitch together pre-existing software to make a seamless experience without reinventing the wheel.

Another thing he said is that if he were a software engineer he would go all in on AI rn.

What do you think about these? Stack stitch and ML your way to success?
