Why are they being criticized from the arbitrary metric of the last 10 years, when both had careers far longer than that? Jon's advice for software is the same advice he used when developing Braid and the Witness, which are both great games and for their time, technological feats, especially from an indie.

Jon's production from the last 10 year isn't even due to bad software methodology from what I observe, it's mainly seems to be because his company is creating a new programming language tailored to games. This doesn't seem to be done to make money, but rather, to try and fundamentally fixed issues that he perceives in game development. It's a lofty goal, and the compiler itself uses the same software methodolgy that he argues for, and it's quite good.

So I don't think this critism is fair. We should look at the arguments they present, and their multi-decade long careers as a measure of thir authority on this subject.
