User blog comment:Emlightened/Ordinals in Type Theory/@comment-27513631-20180128101002

Type theory is actually rather relevant and useful to googology - for instance, it has recursion on well-founded trees (eg ordinals with fundamental sequences) as a primitive concept, and some theories which aren't even googology-orientated are stronger than KPM, all wrapped up in a neat bundle.

There are even extensions which are completely fresh and new to googology, such as the resource-based linear logic and corresponding linear type theory.

What would we want to put on a "type theory" or "introduction to type theory" page?
