EXCERPTS: Tipler theorized that an ETC would be assisted by self-replicating robotic explorers (von Neumann probes) that would spread from system to system, facilitating the arrival of settlers later. As he wrote:
The idea that humanity is not likely to come into contact with an alien species but could learn of their existence through their robotic emissaries is a foregone conclusion among many SETI researchers. And it certainly makes sense. Why send a crewed mission on a multi-generational interstellar voyage fraught with hazards and no guarantee of success when you can send self-replicating robots? In addition to not being vulnerable to cosmic radiation, these probes could expand outwards ad infinitum, carrying messages of greetings to anyone they encounter.
[...] Of course, this raises the question: if we’re likely to find bits of an intelligent civilization’s technology rather than members of a civilization itself, why haven’t we?
[...] In a recent study, mathematician Daniel Vallstrom examined how artificial intelligence might be similarly motivated to avoid spreading across the galaxy, thus explaining why we haven’t seen them either!
[...] Vallstrom argues that cooperative societies and super-AIs would need a good reason to pursue exponential growth and settle an entire galaxy, eventually culminating in a Kardashev type III society. In addition, he posits that evolution would not necessarily favor rapid or exponential reproduction...
[...] there is the question of where we should look for super-AIs or robotic space explorers. First, Vallstrom states plainly that advanced civilizations and super-AIs would not be likely to contact us since they would be unlikely to benefit from it. Simply put, a highly advanced species would have little reason to contact a less advanced species, not unless the cost of doing so was small or there was mutual benefit to be had. “For example, we probably wouldn’t fault old societies or super-AIs for not helping, say, the dinosaurs or the Neanderthals,” he writes...

“In addition to a rocket technology comparable to our own, it seems likely that a species engaging in interstellar communication would possess a failure sophisticated computer technology… I shall therefore assume that such a species will eventually develop a self-replicating universal constructor with intelligence comparable to the human level… and such a machine combined with present-day rocket technology would make it possible to explore and/or colonize the Galaxy in less than 300 million years.“
