Agree on most parts except for 'tango between us and computers'.

Computers will always be servant to men because what separates humans from objects also applies to computers.

The idea of computer or any machine taking over the world is predicated on the assumption that they would have the motive and desire to do so. However, machines are not sentient beings, and they lack the capacity for self-awareness and emotions. This means that machines do not have the desire to take over the world or any other motive, for that matter.
