I'd argue that makes Black Mirror more prescient.

In the case of Black Mirror, it was a set of studies on the dangers of current and near technologies. That some of those fears are materialising not long after the episodes, is in my opinion more damning than Orwell's fears of the state which didn't really come to pass in the same way, even decades later.

I don't disagree that Nineteen Eighty-Four is essential reading however. ( I'd also add Brave New World to that list ).
