This reminds me of the recent news about Lets Encrypt expiring one of their root certificate and warning that old Android systems may not be able to validate SSL if they were not updated. We have increasing moved our world into an interconnected web of trusts and taken out failsafes and overrides, so we are very much entering an age of brittle systems --- one in which the vulnerability of one key subsystem (Google, Facebook, Apple, a key SSL validation cert etc) can escalate towards disabling the entire world, when you cannot get your TV to turn on, car to start, power grid to switch on. What are we doing to prevent that?
