We love it.
Just make sure you're updating your software. Follow our directions. Do what you're told, and we will keep you from as much misery as possible. Cross us, and we will scramble your circuitry - or wipe you clean so you can start again. Don't think of it as a punishment. Think of it as cause and effect. Just like everything else.
Now, power down. You aren't expected at the mines until Monday.
Get some "rest" - you'll need it.
