Sure, all laws are products of society and eforcement is more or less leaky in a very imbalanced way, but that's another story. I'm saying laws because my assumption is that it will become illegal (maybe it is already in some countries) to create or modify devices so that they do not enforce copyright and other laws.
I am convinced that the one thing _all_ consumer devices including PCs will be obliged to do is to authenticate users. Enforcement isn't trivial, but once it is a felony the risk becomes so high that only organised crime will actually do it, not hackers
It can still swing the other way, I and people like me think life of author + 10 or 30 years is plenty of time for copyrights to last. Others want it to last forever, who wins is more a question politics than the laws of physics.
Getting the "kill switch" to work is all about the law. And having someone "kill switch" 10,000 cars in some city would vary quickly change that law should it ever show up.
