No one ever defined programming languages as being things that can do loops and conditions. So this quote can't be valid. This is in the same vein of his argument that HTML is nowhere define in the Standard as being a "programming language". Instead, and this much I fully agree, HTML is a markup language. The debate of whether it isn't also a programming language apparently is still alive. You know my opinion.
Write down a hundred times:
HTML is a data format, not a programming language.
You are allowed to use any programming language to write a loop that writes that text 100 times. You are also allowed to try to do that in HTML.
