Imperative languages have this huge benefit of having implicit state. Both humans and machines are really good at implicit state attached to time. When reading the cake recipe, you know that after finishing the first instruction the oven is preheated, the pans are greased and we have mixed a batter. This doesn’t have to be explicitly stated. We have the instructions and we know what the resulting state would be of performing the instructions. Nobody is confused by the imperative recipe. If I was able to actually finish writing the functional recipe and if I showed it to my mom, she would be very confused by it. (at least the version that doesn’t use monads would be very confusing. Maybe a version using monads wouldn’t be as confusing)
