It’s not stupidity. You need to invent the tools that are needed to make the tools that make the tools that make the tools that make the thing. China still hasn’t independently invented most of those tools yet, so they’ve been relying on finished tools from other countries. Being smart doesn’t wipe away the decades of research needed to make something. We all expect China to eventually be able to make an equivalent tool, but they’re working with a handicap of inexperience which was expected to take years of dedication to overcome. Which is why everybody is skeptical that China made this independently without outside help or knowledge.
