philosophers, physicists, technologists and, yes, comedians have been
grappling with the idea of our reality being a simulacrum. Some have
tried to identify ways in which we can discern if we are simulated
beings. Others have attempted to calculate the chance of us being
virtual entities. Now a new analysis shows that the odds that we are
living in base reality—meaning an existence that is not simulated—are
pretty much even. But the study also demonstrates that if humans were to
ever develop the ability to simulate conscious beings, the chances
would overwhelmingly tilt in favor of us, too, being virtual denizens
inside someone else’s computer. (A caveat to that conclusion is that
there is little agreement about what the term “consciousness” means, let
alone how one might go about simulating it.)
<p>In 2003 Bostrom imagined a technologically adept civilization that
possesses immense computing power and needs a fraction of that power to
simulate new realities with conscious beings in them. Given this
scenario, his simulation argument showed that at least one proposition
in the following trilemma must be true: First, humans almost always go
extinct before reaching the simulation-savvy stage. Second, even if
humans make it to that stage, they are unlikely to be interested in
simulating their own ancestral past. And third, the probability that we
are living in a simulation is close to one."</p>
