Once the wiring becomes generally bad, the cost of repair, and the difficulty in repair will be prohibitive.
Add to this that components used all over vehicles, (window switches, actuators, dash controls, etc) often utilize microprocessors, they will not be economical for the aftermarket to support.
While it is true that modern vehicles are in many ways superior, I do not think that this will translate into the years of viability that we have become accustomed to.
Even today, new vehicles that incur electronic gremlins can be difficult to resolve, this will get even worse as vehicles age.
