It's a bit like cutting wood. Cutting wood can feel terrible. You do it every day because you have to. Along the grain, in wet wood, with a handsaw.

And then, one day you discover the chainsaw, and the fact that you should cross cut.

Suddenly cutting wood no longer feels terrible, it's smooth, stuff works the way you expect. Your chainsaw turns out to have features for all kinds of wood and for many different kinds of joinery that you were hand carving before. It turns out that your chainsaw can be used to control an army of chainsaws without having to do anything at all. You just declare it to be so and it works.

Instead of focusing on your tools all day long you find yourself focusing on the thing that you are actually trying to solve. Where you needed 50 people before, now you need 5.
