What I find most intriguing about this is the how a law that was enforced only 50 years ago has so quickly become abhorrent to the majority of the population. It's an interesting thought experiment to consider which laws we routinely use today to punish people will become morally unacceptable in the next 50 years.
Copyright and patent laws, and laws used against Snowden's whistle blowing are some obvious ones that are due for changes, but what's more interesting is if history continues to repeat itself it seems likely that some things we consider wrong now will become acceptable in the near future and the reverse is also true. This is much harder to predict.
(Humans driving cars is a reverse example. I think in the next 50 years it will become illegal for humans to drive cars manually except on private racing circuits)
