This also shows in how quick you can iterate. The "REPL time" in mechanical engineering has decreased a lot with CAD software but it's still insanely long compa

This also shows in how quick you can iterate. The "REPL time" in mechanical engineering has decreased a lot with CAD software but it's still insanely long compared to software development. I used to work in a lab with a researcher who designed complex mechanical systems with lots of rotating parts made from rare and expensive materials. Everytime he needed even the slightest modification he had to wait for at least three months to have a new part machined.
