It’s only less complicated if you exclude the years of research into the techniques and we’re seeing delays manufacturing because those are not easy to scale. This work started in the 2000s so I think it’d be closer to thinking of how long it took to build a bomb after you had developed the physics, built the mines and processing systems, etc. To me it really highlights how easy it is for us to forget how much science depends on less publicized work - there must have been hundreds of people whose careers went into the manufacturing techniques alone.
