Which speed in which industry? Speed of having the idea, speed of creating a early mockup, speed of creating the prototype, speed of proof, speed of creating the process to replicate at scale, speed of mass production, speed of maintenance and evolution tasks, speed of support, speed of dismantlement, speed of keeping track of all the damn conflicting priorities between all speeds?

In building/construction industry, certainly one might expect delivery speed to matter, and humanity have literally millennia of experience in the domain, and yet it’s notoriously known to go through the roof all the time.
