Near-zero.software's speculative fiction piece imagining 'Software Mechanics' — domain experts who fix AI-generated code's specification gaps rather than the code itself — resonated strongly with HN practitioners at 191pts/102cmts. The central insight (the 'ground moved' problem): ~60% of regenerated-software failures happen because external data sources change under a static spec, not because the AI wrote bad code. The piece introduces the mechanic's paradox — prevention is always cheaper than the fix, but humans reliably pay for crises instead.
