> Micro-optimizing each line of code as it is written, "because it is fast", without even bothering to use a profiler.

With the CPU, MMU and OS architectures of that period, it wasn't particularly hard to infer what was fast without profiling it. The slow rise in complexity at all 3 levels now makes it hard for even extremely experienced close-to-the-metal programmers to understand what will be fast or slow without a profiler. Times do change, in fact.

Yeah, except the world has moved on from PDP-11, no need to keep asserting something that isn't no longer true.
