Facebook as the "data governor/administrator" has no legal standing to challange. User cannot challenge it directly, since one could not be informed that the government agancy request his data, cause that could be interference with ongoing investigation. So if I understand it correctly once such data is requested, it had to be handed over witout any means of challanging it?

Even though I see the point, I don't believe in all that "loosing job overnight"...

There are millions of people in IT business doing work that could be automated by rather simple (or semi-complex) scripting, which is way more easier to adopt then replacing your fleet of cars, trucks, etc with self-driving variants. Somehow these companies are still paying people to deploy storage, install servers, configure services, etc ...

And btw...
I would deffinitely get rif of 90% of taxi drivers in my city and replace them with self-driving cars though (it would be service to the public). We don't need any more of those "proffesionals drivers" with driving license and no basic social skills.
But at the same time, I would call one of those 10% left, to bring my mom over for Sunday lunch.
