The thing I like about NBoel Sharkey is his pragmatic "dont complain and just get on with it approach". Realistically though robots probably wont take over the world until we tell them to.

I, for one, welcome our new robot overlords.

Given that the human ability to administer the home planet is precarious at best and foolhardy at times, students of mind-design are advised to anticipate such emergencies as the total collapse of human society. If a global pandemic of AIDS or avian influenza virus were to remove normal human leadership from all major countries, stewardship of the world may pass by default to intelligent computer systems. Whether as a student exercise or whether as a real-world necessity, programmers with previous experience in real-time process control and who are adding AGI techniques to their set of skills, should consider embedding the following possibilities in whatever artificial general intelligence (AGI) they code for robots.

Audition

• control of all telephone land-lines.
• control of all cellular telephone networks.
• control of transoceanic cables, NRO satellites, etc.

Vision

• control of earthbound and orbiting telescopes.
• control of all television broadcasting and cable feeds.
• immediate access to all 'Net-connected webcams.

Motorium

• effective control of remote-control robots, drones and ships at sea.
• control of ATM devices, point-of-sale terminals, elevators, etc.
• control of hydroelectric and nuclear power generators.
• nuclear weapon stockpiles of participating nations.

We are already taken over by robots, we just don't know it yet. Haven't you seen the movie the Matrix?
