> every bottleneck we remove immediately leads to a further increase in the amount of code we produce
Less-than-great news for code artisans. You can be brilliant, but can you divine the Right Way to Write It if you're up against an apparatus that starts at "pretty good engineer" then brute-forces its way down an exponential search tree?
It actually scales by "going wider" and being able to do more things rather than iterating on the same code over and over again. If you can only write X amount of code per day because of some limitation (human attention, source control, CI, whatever it is), you would of course use that energy on the highest priority and highest value work. As we remove scaling issues in source control, for example, we can just "do more things" without worrying about bringing down infrastructure.
