I think the point they were trying to make is that although we might not see the complete collapse of these industries now, there is a good chance it is still coming. They might already be dead by something already created but the knowledge just isn't widespread yet and is sitting in someones thesis just waiting for another person to try a practical version of a now theoretical concept. As to their other point getting rid of the programmer is very much on peoples todo list right now. It's a massive cost center. To think this one line of work is somehow immune from this trend seems short cited. I am sure the horse caretakers had a hundred reasons why they would survive automobiles until they didn't.
