In fact, a compiler is doing part of the job of an old school programmer who only had machine language to work with, just as mathematica is doing part of the job of an old school mathematician or physicist who needed to work out integrals by hand. It's not "AI" in the sense of actual intelligence of course, more like a labor saving device. That said, it's entirely possible that letting the computers do these tasks, something important has been lost. It's more obvious in programming when people ship 10 or 300 megabyte "hello world" output when entire operating systems used to fit in 4k binaries. Might also be true in mathematical physics anyway, as they haven't exactly covered themselves in glory for the last 40 years.
