ETs & DNA Synthesis: Is Seti Dangerous?

The idea that the passive SETI can be dangerous is not new. F. Hoyle suggested in the novel "Andromeda” a scheme of alien attack through SETI signals. According to the plot, astronomers got alien signal, which contains a description of a computer and a computer program for it. This machine creates a description of the genetic code of substance. On the basis of this code was crated intelligent creature - Andromeda girl, which, working together with the computer, creating advanced technology for the military. First, people do not trust it, but then they see that it makes useful ideas. However, the main characters realize that the computer acts hostile to human civilization and he destroys the computer, and the girl dies. This scenario is fiction, because most scientists do not believe in the possibility of a strong AI, and, secondly, because we do not have the technology that enables synthesize of new living organism only on its genetic code. Or at least, we have not until recently. Current technology of sequencing and DNA synthesis, as well as progress in developing a code of DNA modified with another set of the alphabet, indicate that in 10 years the task of re-establishing living being sent from space on the computer codes would be feasible. The researchers emphasize however, that the research is still in its initial stages, and as they "sail in unsheltered water," it will take some time before the full significance of the research is understood and its technological potential is fully evaluated.
