Nice write-up. I’ve always felt that Amdahl’s Law gets oversimplified in software discussions. The real bottlenecks tend to be architectural rather than purely parallelizable tasks.

Thanks for sharing both links. Seeing Amdahl’s original framing alongside Gustafson’s optimistic reinterpretation really helps clarify where the architectural limits start to dominate once workloads scale.

Neil Gunther extends Amdahl's law to the Universal Scalability Law in https://www.perfdynamics.com/Manifesto/USLscalability.pdf (pdf). He uses it to help model a system's scalibility.
