Laying brick is hard. I bricked up a small gap in a two-foot-tall brick wall in my back yard recently. It took me literally all day, and looks exactly as messy as someone who lays bricks might expect from someone who uses a computer for a living.

Watching those people on youtube who make tutorial videos that go super fast and make it look really easy... You can record yourself writing a python script and make it look easy. Those people are pros, and have skills and experience to back it up. It isn't easy.
