Think of it like this: would you use slaves to build your pyramid with the technology of that era? It’s high tech, requiring the smartest people you have available. It can be exponentially more expensive if the workers make mistakes. Naturally you want them to make as few mistakes as possible. You don’t let slaves nowhere near the important stuff.
