Consumer hardware becomes infrastructure only when the complexity disappears

Powerful consumer machines can run surprising workloads. That does not automatically make them useful infrastructure.

Hardware differs. Memory behaves differently. Drivers, runtimes, sleep states, networks, and failure modes differ. The interesting layer is the one that turns that variation into a predictable service.

Until then, we have capable machines, not a dependable pool of compute.

The test is not whether the system can complete one impressive run. It is whether another person can rely on it without learning why that particular machine is different.
