Warning signs for the coming age. A full description of the meaning of these signs can be found on the FlickR page of Anders Sandberg. Examples of signs include:

Self-replicating device

Self-replicating devices are potentially the most powerful technology of all, since they can increase their reach exponentially in suitable environments. It also raises risks of arms races (whoever builds and releases one first wins), unwanted replication (the sorcerers’ apprentice) and slight misbehaviour of the devices that becomes dangerous as they become numerous.

Motivation hazard 

As we learn to affect our brains better there is an increased risk for addictions, to gain pleasure from something harmful or that we edit ourselves to like our current state no matter what. The poppy represents such motivation traps.

Memetic Hazard 

A black lightbulb to represent really bad ideas.
