"It does not tell us where advanced ETI’s may be dwelling or what they’re up to (are they outside the Galaxy? Do they phase shift outside of what we regard as habitable space? This is a serious shortcoming because the answers to these questions should help us determine not just where we should be looking, but they can also provide us with insight as to the makeup of advanced intelligence life and our own potential trajectory."In other words, Dvorsky concludes, post-Singularity machine-based intelligence may represent the most common mode of existence for late-stage civilizations.

In 1961 the Russian cosmonaut Yuri Gagarin became the first man to orbit Earth, while Frank Drake (image below) developed his now famous Drake Equation, which estimates the number of detectable extraterrestrial civilizations in our Milky Way galaxy, based on current electromagnetic detection methods.
