It's funny you think it's going to be undone. We are not going back to a time where humans type code for any serious commercial product. As they said in the article:
Fowler isn’t saying developers will stop reading code, or that software engineering is done. His point is that manually typing code line by line, in an editor, is becoming the least interesting part of the job.
But there will be a point where very little code is written line by line by humans. Though I suppose most of it was already copy pasted anyway.
