Almost always when a catalytic converter dies it is because there's something wrong with the car that damaged the cat. I never actually worked in a smog shop so I can't give meaningful numbers but we had plenty of 20-30 year old test cars come through the school shop with original catalytic converters that still worked fine. And I was not claiming that no CO comes out of the tailpipe of modern cars, just not enough to be a meaningful issue, it's not a particularly persistent environmental gas outside of confined spaces. It's not a major smog component, it's just toxic if it's allowed to build up, and most modern cars aren't putting out enough of it for it to build up to dangerous levels without REALLY trying.

something like the o2 sensor reading incorrectly, or oil or coolant getting through the exhaust... or high heat...

well it's hot as fuck out there, and no car I know lasts forever. these things have a finite work life and then become markedly less effective, and they only capture a band of the problematic emissions. and not forever, just as long as everything is working well.

when they aren't stolen etc.

spewing CO and other pollution, when we have the tech to swap the vast majority of drivers to something markedly less polluting.

world's on fire yo, no reason not to just go electric for everyone that can.

I mean, you're preaching to the choir, I haven't owned an ICE car in about 7 years, and no car at all for about 4 years. I'm just trying to correct misrepresentations. Concern about CO emissions is a silly reason to be concerned about modern ICE cars, it's not a big issue really. Realities of fossil fuel dependence and use and its affects on the environment both locally and worldwide seem like the larger concerns by a large factor.
