The brothers discuss the advent of battery run devices such as clocks and their move into no-touch devices, such as in washrooms (faucets, soap dispensers, auto-flush toilets), locks on lockers and safes, and how this advance in society has moved forward without the ability to maintain it. What happens when the batteries die and who looks after changing them?
