I prefer "the bottleneck is understanding" framing.
The author is nibbling at the same problem ultimately, but i don't think "hey one strategy is we could just let cognitive debt accumulate so we can go faster!" is a particularly insightful tool in the toolbox. Don't misread me, i'm not denying it can be a valid strategy.
Instead i want to read about insightful strategies for optimising that system-wide bottleneck we have: understanding.
Tell me about how you managed to shift to a higher level of abstraction, tell me about how and when that abstraction leaks. Tell me how you reduced the amount of information that has to flow through the system bottleneck.
