What they really means is they previously had no valid metric to measure productivity of developers before either. AI or not.
Which reflects another thing I’ve seen at work. A lot of what AI coding has enabled is diving headfirst into quagmires. Our costs have spiked - not just because of the token spend, also because we gotta pay the cloud platform to run all these new services, operators to operate them, marketers to market them, etc. - but revenue hasn’t budged.
Eventually I got tired of it and got back to work.
