		<description>Hi to everyone.Perhaps I&#039;ve been watching too much Terminator,amd Matrix movies, and reading too many &quot;grey goo &quot;articles ,but where is the off switch for these little DNA robots?What if the first functional molecule these robots create has a small genetic &quot;deficiency&quot; in its molecular structure that allows it an &quot;evolutionary advantage&quot; so to  speak, over the less well endowed prior version of that particular molecule. However, what if the molecular variant has unintended consequences, or,&quot;side effects&quot;, which, for example, would eat through the molecular structure of all the concrete on Earth, or perhaps all the steel and metal alloy compounds. Once released into the environment, it could supplant the natural molecule, similar to the danger of genetically engineered crops supplanting more robust, natural varieties.I&#039;m just an amateur ,who reads this stuff for fun.
