Why Isn't Functional Programming the Norm? [video]

Richard Gabriel’s famous essay “Worse is better” (https://www.jwz.org/doc/worse-is-better.html) is an interesting perspective on why Lisp lost to C. In a way, the same arguments (simplicity vs consistency vs correctness vs completeness) can be made for why functional programming lost to OOP.

But those philosophical perspectives aside, personally I find my brain works very much like a Turing Machine, when dealing with complex problems. Apart from my code, even most of my todos are simple step-by-step instructions to achieve something. It’s easily understandable why like me, other non-math folks would prefer a Turing Machine over Lambda Calculus’ way of writing instructions.

This could be why OOP/Imperative was often preferred over FP.

Exactly this. How baking a cake in FP looks like:

* A cake is a hot cake that has been cooled on a damp tea towel, where a hot cake is a prepared cake that has been baked in a preheated oven for 30 minutes.

* A preheated oven is an oven that has been heated to 175 degrees C.

* A prepared cake is batter that has been poured into prepared pans, where batter is mixture that has chopped walnuts stirred in. Where mixture is butter, white sugar and brown sugar that has been creamed in a large bowl until light and fluffy

but now that you've written the cake baking data type, with a little small tweak, you've got a bread baking data type.

I'd rather have a baking class that takes an argument for what I want to bake, either bread or cake, and spares me the details of how baking is done. I don't have to know that a preheated oven is one that is at 175 grades etc

And when your oven has a problem with it's heating element you'll have no idea why your cake didn't turn out well. We're supposed to be engineers, right? Learning how things work is good.
