Nanohysteria comes into different varieties too. Type 1 nanohysteria is represented by greed driven “irrational exuberance”, and is based on the idea that nanotechnology will change everything very soon, as touted by investment tipsters and consultants who want to take people’s money off them. What’s wrong with this is the absence of critical thought. Type 2 nanohysteria is the opposite - fear driven irrational paranoia exemplified by the grey goo scenario of out of control self-replicating molecular assemblers or nanobots. What’s wrong with this is again, the absence of critical thought.In any journey it's natural to imagine what the destination will be like. There's nothing wrong with speculation but problems come up when we mistake our speculation for reality.
Developments in nanotechnology are starting to come thick and fast and each one can seem like the last step before utopia or world devastation. The potential of nanotechnology seems limitless -- so much so that it's easy for even the most intelligent person to get lost in fantasy.
Just about any prediction about the future of nanotechnology, from the most optimistic to the most dire, could be true -- but it's exactly when anything seems possible that it's most crucial to focus on what we know now.
