I agree.

Further his exposition on `Either a b` was built on a lack of understanding of BiFunctors.

The icing on the cake was his description of his own planned type theory. What he described was, as I could decipher from his completely ignorant ravings, a row-based polymorphic type system. However he passes off his insights as novel rather than acknowledging (or leveraging) the decades of research that have gone into type theory to describe the very system he is trying to build.

Worse, he continued to implore his audience to spread FUD about type theory, claiming several times, "it is wrong!"

Well, in his defense, type theory is supposed to make software engineering simpler, not more difficult. So if even he doesn't understand it, then how can we expect a random programmer to?

Well software engineering is the only engineering field that produces half baked unreliable crappy solutions continuously. Other fields cannot afford such attitude towards products. I think a simple (inferred) type system is pretty useful to increase correctness and it helps you to increase reliability (even though it does not avoid all of the mistakes you can make in software).
