I read this as it being not that people are incapable. But at scale it's hard to track accidents, so tech needs to be used otherwise it's impossible. To do so at scale inside of a warehouse like Amazon's
This tech is absolutely not about accidents, it's about making sure workers spend every single second of their time producing revenue and not talking to each other, going to the toilet, having a break, discussing their shitty working conditions, that kind of stuff.
