Not sure among devs, but I do know that in other positions in typical corporate bureaucracy, people have a propensity to not report their own automations or productivity gains upward, because the reward structure isn't there.

Early on in my days as a sysadmin, I automated a ton of my role when the rest of the team was still doing ClickOps. The reward for doing so was more work and expectations without the additional pay increase to justify my new found productivity. That happens all over the workforce, and so people will just keep it to themselves. I learned my lesson at that first job real fast that if I'm able to have the same, or greater output, for half the time, I keep that to myself so I can use the automation to free up my own time instead of have it filled by the company.

I wonder how much of that is happening now with AI in non-technical roles.
