Because all humans are 100% fungible with all other humans. So, you can take whatever old humans you have, throw them away (or make them want to leave), and then replace them with all new humans, with zero negative effect on anything. Rinse and repeat.

Human experience means nothing. Anything that does have meaning gets encoded in the system for the mindless humans to implement.

That’s my take on the view from the top, based on my time working at AWS.
