@jjfphd I think it will be more like a drawn out decline than an apocalypse. It will probably take 100 years or more until the Industrial Age is finally over and the old civilisations are gone. Until then, things will get worse and worse, sometimes in a great catastrophe that kills many people and destroys many things, but most of the time, it will be rather quiet and boring, just entropy doing its thing and humans being unable to repair their cities and infrastructure quite as fast would be necessary.
