“50 years from now, I can’t imagine people programming as we do today. It just can’t be." Dear writer, let me introduce you to FORTRAN, COBOL, LISP, or BASIC. These are alive languages, all 50+ years old. Coding didn't change much. The languages, the methodologies, the ideas change, but the approach is the same, and whoever thinks this will soon (50 years is not _that_ far) changes, have never had to debug something…
(And even just looking at languages, Fortran 2008 is hardly recognizable as compared to FORTRAN IV)
