Robots do bake. Actually, a lot of the food you eat is partly made by machines. It’s how we aren’t all starving right now, and why famines are so much less common. As good as handmade bread is, it couldn’t feed 8 billion people. We have bread loaves in the supermarket made by machines, and we are better off for it.

It’s been done a lot, but its kinda pointless as any noise improvements from the shape are obliterated by the bad surface finish.
