"Software would no longer be a set of features in an application. Instead it would be millions and millions of simple transformations, which could be conveniently mixed and matched as needed." Right, so instead of writing lines of code, we'd mix and match from a pool of "transformations"... which would require some means of describing how those transformations should be combined... which is pretty much analogous to writing code. This prediction has been made repeatedly since 1950 and it has never happened. There are just as many good explanations as to why, so I won't bother enumerating them. I have no idea why new people keep coming up with this same idea.
