    Not entirely. The Bayesian while rejecting premature certainty, might
    well decide that certain activities were unwise. E.g., broadcasting our
    position loudly. It might be prudent to restrict the noise level
    generated by our civilization considerably, as one reason for there not
    being a large influx of tourists might be predators making the
    passageways dangerous. Such predators would necessarily have a much
    higher level of technology than we do, so we would be easy prey,
    presuming that they liked our habitat.

    OTOH, I consider it more probably that people living in long-lasting
    civilizations are just too comfortable to leave, and that the ones that
    move into macro-life colonies find that re-adapting to life on a planet
    is an apalling idea. That past a certain point physical population
    tends to dwindle, so there is less point in colonization (we may have
    reached that point). And that people tend to migrate into
    computers...so we should be looking for signs of computronium.

    But the first possibility remains a possibility. And finding
    computronium wouldn't disprove it.

    N.B.: Another plausible scenario is that many of the intelligent
    entities are less mobile than we are. But these don't present any
    obvious threat to be guarded against. And his doesn't indicate that any
    of the other possibilites is impossible. Space is deep.
