This would stop the currently exponential pace of growth from outpacing what society, and regulation, can adapt to. Thus avoiding the inevitable crash that will happen when we lose control of the exponentially accelerating train of technology, and it flies off the rails.
the actual balls from balls to the wall are in the building
I think these are actually the balls from “balls out” when the engine is going full speed the balls swing way out and are spinning around.
IIRC, “balls to the wall” refers to ball-shaped knobs on the throttle levers of a lot of aircraft. To go fast you push that lever as far as it goes “to the wall”
Balls any smaller just wouldn’t do justice to such a powerful machine
