However, if you substitute intellectual resources for natural resources, you make a very good point. The one resource that no techno-civilization could reliably produce is a new way of looking at things, or a new way of thinking. So if they were motivated by some aesthetic of learning, they might seek to communicate with other techno-civilizations, or even with primitives. If we accept that as a working premise, then we are left with two likely solutions to the Fermi paradox. Either there are no ET techno civilizations, or else, they are secretively watching us. Ooh.

Interesting, except I disagree about the natural resources part. Creatures of sufficient technological advancement would have learned transmutation of elements, and be able to create whatever natural resources they needed.
