Xiangma: AI tooling stops at the ROI boundary — engineers shift to filling the cracks

ClaudeCodeLog · x · 2026-08-22

Xiangma (founder of Xici) argues engineers will never disappear, but how they work will change: tooling always advances until its ROI drops below human labor, after which more humans are needed to fill the remaining gaps.

His dishwasher analogy: a machine replacing 3 dishwashers is the high-ROI phase, but the odd-shaped pots and scorched pans — the last 5% — would cost ten times more to automate than the first 95%, so keeping one human is cheaper.

He adds that stronger tools expand total industry output: the restaurant serves more guests, creating more edge cases, so you lay off 3 regular dishwashers but hire 2 specialists. For software: AI will absorb standardized coding, but the industry's explosive growth brings boundary cases, system integration, and business understanding that still need humans.
