Yeah, unexpected long term manufacturing f... ups caused by pushing design limits with software able to alter voltages on critical parts of a c.p.u, no fail-safe against critical parts of substrate getting too hot intermittently causing progressive failure of nano-transistors, my equipment is so old it won't bother me I don't think.
It's not the least charm of a theory that it is refutable. The hundred-times-refuted theory of "free will" owes its persistence to this charm alone; some one is always appearing who feels himself strong enough to refute it - Friedrich Nietzsche
