grug miss big brain benefit for types. Grug says the main benefit is auto completion, I think the real benefit is to making code changes.

If I update a type, the compiler will tell me every single location where I need to make a corresponding code change. For grug: change type give red squiggle, make change code good

Also, grug makes a good point about the temptations of generics, but I think they’re exaggerating the impact to the speed of development.
