Honestly this fear is overblown. Unless you’re making pastries, baking is relatively straightforward and forgiving. Breads, cakes and flatbreads love you and want you to have fun. Experimenting with vegan substitutions, gluten free baking and scaling batch sizes helped me feel much less intimidated by recipes, you learn what role the ingredients are playing and how to adjust if you add too much, too little, or too not the right thing.

Because they want to do a lot of it and faster than a home pc could so they can offer it as a service.

What do you have against philistines?
