I think that part assumes that people are honest. If not human checks the books, then you could slip a malware on the accounting bot and have it slip a million dollars into a Swiss bank account. If no one looks regularly, you'll never know until you're out of money. Same with driverless delivery - just change the address and have the machine at the receiving site report that the delivery arrived. If no human is there, you're not gonna catch it. We already have skimmers on automatic payments collecting, we have identity theft, and people steal from self checkout all the time. Machines are great and efficient, but they're not smart enough to question orders. A human is.
