What is the theme in The Andromeda Strain by Michael Crichton?

Scientific hubris is a theme in the book. The scientists in The Andromeda Strain engage in an exercise in futility. Their quest to save the world from global destruction is a crisis invented by the very men who seek to resolve it. Jeremy Stone is the personification of scientific hubris in the story. As the creator of the Wildfire Project, his vision guides the project from its initial conception through final construction of the top-secret underground laboratory. His goal for the Wildfire Project is nothing less than to save humanity from mass destruction. Stone conceives of a theory that man's first contact with alien life will be with an alien bacterium.
