George Dvorsky gives us:
Seven ways to control the Galaxy with self-replicating probes
When you think about it, that’s a pretty modest title. “Controlling the galaxy” just sounds a lot folksier than “ruling the universe,” doesn’t it?”
Anyway, seeing as I expect that most of the galaxy will be explored by self-replicating probes while I’m off on my retirement cruise, this topic is of personal interest to me. Of course, if technology advances the way it ought to, and no retirement cruise is necessary, I hope to participate in the exploration and settlement of the galaxy in uploaded form. That would fall under item 4 on George’s list:
1. Exploration
2. Communication
3. Working
4. Colonization
5. Uplifting
6. Berserking
7. Policing
This is good reading, especially the analysis of that nagging question “Where are all the probes?”
