The rise of autonomous weapons and other technologies could bring the world at the brink of a robot war. Experts believe that if United Nations continues to delay negotiations on the use of autonomous weapons, the results could be disastrous.

As of now, there is no control or ban over the use of autonomous and other emerging technologies, despite several campaigns have been organized by the experts to do so. However, the U.N. has been criticized for not responding swiftly to the pressure from the activists and artificial intelligence experts.

The critics argue that the U.N. is taking too long to restrict the use of autonomous weapons while the associated research and development are being carried out by the military. Even though the issue is under discussion at the U.N. general assembly in New York, experts fear that the decision might not be quick enough to stop the weapons from being deployed.

"A lot of money is going into development and people will want a return on their investment," said the U.N. special rapporteur Christof Heyns, in a statement. "If there is not a pre-emptive ban on the high-level autonomous weapons, then once the genie is out of the bottle it will be extremely difficult to get it back in."

Experts also believe that the U.K. and the U.S. are trying to reach an agreement that only includes restriction on emerging technologies. That means, any weapon deployed while the U.N. negotiations are on, will be beyond the reach of the ban and not subjected to any restriction.

While negotiation is being delayed, a number of nations, including the U.S., U.K., Israel and South Korea are testing their semi-autonomous weapons and placing them along their borders.
