I'm spending more than my salary on AI, about $16k last month.
Employees at most companies are bottlenecked on things other than code, like manual testing or waiting to compile.
Companies like Meta, mentioned in the article, have invested billions into solving these problems with distributed build/test farms and custom review infra.
I'm personally seeing this, because my role shifted from "write GPU test code" last year to "rearchitect our build and review processes" this year as this bottleneck becomes obvious.
Reading your post, it is clear to me that management and engineers will rediscover the theory of constraints at some point if they can connect the dots.
