I'm sure everyone here has thought about the implication of automation on the future of employment. But I personally hadn't considered the impact specifically on social security systems in particular. Interesting!
I must admit, this all seems very murky to me. When does a collection of hardware running some software become a "robot"? If I can replace an intern with a Python script, does that script start having to pay social security too? If one were to take a principled stand on this, each business should have to estimate however many people have been "automated away" and pay that much social security. Maybe we could back-date the impact of automation to the invention of the steam engine, perhaps, since this is clearly an ongoing trend and not something that is only starting in 2017.
And why does a piece of equipment need to be deemed a "robot" in order to for someone to be liable for damages it might cause? I'm no legal expert, but my understanding is that there are already plenty of laws and judicial precedents in place regarding such liabilities.
