Not sure if this goes in here, but I'll be talking about my type theory powered by metaprogramming over at twitch tomorrow: https://twitter.com/AndreKnispel/status/1247914790598688772?s=20
Some people here have seen my talk about it at the Statebox Summit last year (https://www.youtube.com/watch?v=QW37iWVSN5Y), and there has been a lot of progress since then. It has some cool features that you don't get in other proof assistants, for example the ability to reason in a logic that has been formalized within the system, without syntactic overhead (which should be fun if you want to write programs in topoi).
I'm planning to give a talk and demo on my work on Meta-Cedille (https://github.com/WhatisRT/meta-cedille) tomorrow (the 9th) at 18:00 (GMT+2) over at https://www.twitch.tv/whatisrt_
