Developing Gate-all-around technology takes time and can involve iterative experiments in which researchers revise a failed hypothesis and test a different structure.

“Uh, all those things take time. Uh, and, and some of it's iterative, where you have to run a Gate-all-around transistor. You say, "Oh, well, that didn't work. Uh, let me figure out what was wrong with my hypothesis and try it again with some different, uh, structure."”
