I'd say that it's decreased, because of how tiny the transistors and interconnects are getting. The CPUs still work today (obviously), but the margins are much thinner than they used to be because they don't design for more than a few years' lifespan.
The 486 was produced in a 1um (1000nm) to 600nm process and runs on 5V+/-5% (4.75-5.25, a 250mV range), with an absolute maximum of 6.5V.
The 14nm Skylake has a core voltage of ~1V, tolerance of a few tens of mV, and an absolute maximum of 1.52V.
Electromigration will likely become a significant source of IC failures in the future.
