Refinement pipelines are everywhere, and they all have the same shape: stages persist even as the executors at each stage change, with the goal being more-efficient output with reduced human input.

Consider Bitcoin mining. The Bitcoin whitepaper described a proof-of-work system. The first people to implement it were cypherpunks running the reference client on CPUs. When the economics became clear, miners moved to GPUs - the same algorithm, a more specialized executor. Then purpose-built ASICs that do nothing except compute SHA256 hashes.

The stages didn’t change. You still need the whitepaper’s theory, the hash algorithm’s specification, and the optimized implementation. What changed was who - or what - executes each stage. Nobody skipped from whitepaper to ASIC. The pipeline was load-bearing.

The same pattern appears in manufacturing, in logistics, in agriculture - anywhere humans have refined a process and then progressively swapped in more specialized executors. The stages don’t disappear; they get encapsulated. You stop seeing them. But they’re still in there, doing the work.

Half-Baked Thoughts#

• Chainsaw origin: surgical instrument
  • General-purpose tools are transition technologies; what follows is always specialization (scalpel, bone saw, feller buncher, harvester)
• “We’re in the GPU era” (software, knowledge work; code goes first) - general-purpose tools with jigs clamped on
• Possibly a Butlerian Jihad addendum: “all work is solved; now what?”
