I keep seeing the claim that "AI" multiplies the productivity of senior developers repeated as justification for FOMO.

The best available data clearly shows that, in terms of *outcomes* at the *team* level, that multiplier is - at best - about 1.1x.

And for the majority, it's more like 0.9x.

We know exactly why this is, too.

1. Bigger change batches hitting bottlenecks like testing, code review and integration

2. Coding was only a small part of the process anyway

* sigh *

@jasongorman You know, the AI Bros solution to this problem is, of course, to have the AI handle testing, code reviews and integration as well, or just skip them altogether 🤷🏻‍♂

@jasongorman

why you measure the senior? AI get rid of the worst developers, not the best.

And there is a whole mass of it. People who did 6 months training , writes a linkedin style resumee, and asks for money.

Is not the senior who fears AI.

As time goes by, a fundamentally harmless invention is taking hold, and its danger does not so much lie in what it actually does—after all, it is nothing more than a statistical language model—but rather in what people believe it does, or might one day do. In other
