    Or, it could be that life is more common in the universe than dangerous
    life, which could explain a biosphere being ignored for millions of
    years. Dangerous civilizations in our vicinity may be reactive rather
    than proactive or predatory, waiting until threats appear or become
    obvious to deal with them. That is a lazy approach to be expected if our
    planet does not really offer anything of value for "predation". Our
    transmissions since the 1940s have probably not indicated much danger to
    them. Even our fairly recent space launches must look like the
    construction of rafts to a civilization with aircraft carriers and
    nuclear submarines. We are not yet underfoot. Ah, worse than to be hated
    is to be ignored...
