Yes it was more of a rhetorical question, e.g. maybe we need to rethink that whole idea of plugging everything into the internet and instead go back to air-gapped "local area networks".
It also wouldn't be a big deal when a supermarket employee makes an old-fashioned phone call (gasp!) to the refrigerator service company when some red light starts blinking ;)
The trained and retained supermarket employees are gone. The refrigeration service engineer has been replaced by an AI chatbot. We can't scale to qualified people running complex systems on remote air-gapped networks.
It would be unfortunate if the red light starts blinking at midnight.
The poor fellow, or gal, now has to endure AI bots while trying to call support on the phone.
