To the great surprise of my younger self I have never seen “it all come crashing down” and I honestly believe this is extremely rare in practice (i.e. the U.K post saga), something that senior devs like to imagine will happen but probably won’t, and is used to scare management and junior devs into doing “something” which may or may not make things better.

Almost universally I’ve seen the software slowly improved via a stream of urgent bug fixes with a sprinkle of targeted rewrites. The ease of these bug fixes and targeted rewrites essentially depends on whether there is a solid software design underneath: Poor designs tend to be unfixable and have complex layers of patches to make the system work well enough most of the time; good designs tend to require less maintenance overall. Both produce working software, just with different “pain” levels.
