> I have been told that when proposing to formalise mathematics these days, you have to explain why you are not using Lean....Amidst the hype around today’s progress, we must remember how we got here. It was not by people following the crowd.

Im not a mathmatician, but in my experience if you are trying to do something novel, you should follow the crowd except for things that impact what you are trying to achieve. Otherwise you spend a lot of extra time sorting through issues on the part that doesn't matter which could be better spent on the novel part.
