About ML-related research, Fong also piqued my interest earlier with his categorification of almost PGMs. Though it didn't inspire him or anyone to bring effective methods of algebra to PGM and improve the base theory, making the exercise really shine. So like with many categorification research it's just a 72-page statement „it can be done”.
