I can assure you, when shit is broken in production and customers are knocking at the door threatening to cancel it is not a luxury to find out these types of things...let alone start untangling the web.
And window repair customers wouldn't exist if it weren't for broken windows! If Bastiat were alive, he'd have a field day with the computing industry and its Freakanomics-like underpinnings.
Anything is possible. Better to focus on what is likely. Did you stop using google over any of their outages? Most people didn't. These things matter, but people in software overstate them.
Software for automatic trading, dosing radiotherapy, controller for moonshot etc will have different requirements on correctness than ordering of search results.
Ignoring these things can have people killed/ruined and they have.
