When I was at AWS over a decade ago, there was endless complaints about the elevator algorithms by engineers, with the usual egotistical tech-bro insistence that they could do better. Things used to really suck at lunchtime when folks would flood to the elevators and be stuck waiting for ages. Those same geniuses could never figure out the benefit of staggering lunch times.

Someone got really tired of it, and somehow organised a hackathon weekend, with the elevator company, and let teams of engineers have at it.

Every single team failed to come up with better algorithms. All the complaints stopped dead.
