I heard it constantly when I worked in tech: "move fast and break things." But when throwing the power on 480 volts after replacing the mag starter on an air compressor might blind or burn you if you did it wrong... that puts a whole new meaning to "move fast and break things."
On my first motor replacement job, the tech who was training me kept reminding me to "slow down". "Slow down." "Slow down". "Going fast could hurt you. Just slow down." When I git push and wait for the CI/CD to finish, I'm not typically worrying about whether or not I might blow up a multi-thousand dollar air-end and take down a food processor's primary air compressor... I've done some crazy deploys in my day, but none that relied on me making sure I didn't cross a wire that could literally blow something up.
The stakes are different and it feels different. You're careful. You use lockout tags and call and respond when equipment is powered on. When I'm literally inside the bowels of a machine that's taller than me inspecting the drive shaft, it's vital that it doesn't turn on.
It's funny how I can see some of the similarities—the unit tests and integration tests and such... you test continuity, you pull on the wires going into your wire nuts. You make sure that you get a successful unload, and that the oil level is still good after running the machine for a bit... but there's still a different feeling. You don't stand in front of the switch you're throwing because if something doesn't go to plan—no matter how many times you check it—the fireball or arc is gonna bite you.
The most risky database migrations didn't get my attention as much as hearing that tech say "go slow, go slow" as I checked my work.
