Some things might not be noticeable, such as disinfecting certain surfaces or performing routine maintenance such as cleaning filters until it’s too late.

You are not going to check if it has been done by monitoring where the janitor goes.

Yep. This is why humans invented trust and consequences, though. Most people aren't dicks if you aren't dicks to them, and I'd rather discover the exceptions and fire them than treat everyone like one.

Trust doesn’t scale. And scaling results in much bigger rewards.

I’d say it’s more accurate that humans have had to rely on trust due to lack of alternatives, but transparency will always be preferred.

You don't need to scale supervision on janitors. You can just hire some people and pay them some money. If you can't afford enough supervisors to keep a vague eye on what's going on, live with dirtier buildings or go out of business.

In general I think some things scale well and others don't. Why is it that HN recognizes outsourcing your tech to try and scale fails but other jobs aren't as worthy?
