I think when people say “destruction of the planet” they are really meaning “our ecosphere and the multitude of species that are currently going extinct”.
Many recognize that we are in a 6th mass extinction period and understand that as the ecosystem goes, so do we. Is the spheroid body of the planet going to crumble or plate tectonics stop working because we’re gone? With all deference to George Carlin, no we know better (we’ll, there is the question about racking-induced earthquakes, but that’s a bit in the weeds).
Nah, they’re run by the laziest chucklefucks you’ve ever met - they’re plugged right into a broadband modem with no firewall running bog standard teamviewer or RDP awaiting any connection (no filtering) because the people setting up and using these systems have no concept of infosec. They know how to set up their industrial system, plug it into the ‘computer thingy’, and hand it off the the municipal water dude who is a flat earth, anti-fluoride, moon-landing hoax, J6-denialist who knows nothing about technology, but wants to run the town’s water treatment from his cell phone.
(not that I’m jaded by small town dynamics or anything)
