In my opinion, it is not true that robot replacing human’s works equal human cannot do working. Clearly, working time will be reduce, but it will require more complicate and professional intelligence job.

Threat of hack is thruth that cannot deny. However, definitely, there are crimes in just society of human. but people didn't stop any system or rules just because of fear from crime. Similarly, even there are countermeasures for hack, minding to use robot is not desirable.
