It's really hard to attribute productivity gains/losses to specific technologies or practices, I'm very wary of self-reported anecdotes in any direction precisely because it's so easy to fool ourselves.

I'm not making any claim in either direction, the authors themselves recognize the study's limitations, I'm just trying to say that everyone should have far greater error bars. This technology is the weirdest shit I've seen in my lifetime, making deductions about productivity from anecdotes and dubious benchmarks is basically reading tea leaves.
