Our Existence (part 2)

Recently I wrote that I was reading Existence (David Brin, 2012), a novel I found so striking I had to post about it before I was even halfway through. Now I’ve finished it, and I still think it’s one of the more striking books I’ve read recently. (Although a little blush came off the rose in the last acts.)

Central to the story is the Fermi Paradox, with a focus on all the pitfalls an intelligent species faces. The tag line of the book, a quote attributed to Joseph Miller, is, “Those who ignore the mistakes of the future are bound to make them.” Brin’s tale suggests that it’s well neigh impossible for an intelligent species to survive their own intelligence.

I’ll divide this post into three parts: Mild spoilers; Serious spoilers; and Giving-away-the-ending spoilers. I’ll warn you before each part so you can stop reading if you choose.

Our Existence (part 1)

I’m not quite halfway through Existence, by David Brin, but I’m enjoying it so much I have to start talking about it now. For one thing, it’s such a change from the Last Chronicles, which was a hard slog with a disappointing ending. (Still worth the journey, though.)

The novel is a standalone, not part of his Uplift Universe, but it apparently can be viewed as a kind of prequel to that reality. However: so far no alien contact, humanity is still on Earth, and computers are not conscious (but AI is very, very good). The year, as far as I can tell, seems to be in the 2040s or 2050s.

At heart, the novel’s theme is the Fermi Paradox; it examines many of the potential Great Filters that might end an intelligent species. But now an alien artifact has been found, a kind of message in a bottle that appears to contain a crowd of alien minds…

The Fermi Paradox

Where are all the aliens?

I’ve mentioned the Fermi Paradox here quite a number of times, but I’ve never made it the main topic of a post. Lately I’m becoming more and more convinced our world is facing a Great Filter, and that we may very well be seeing one answer to Mr. Fermi’s interesting paradox.

Which is a response to the Drake Equation, which I have made the topic of a post.

Essentially, the Drake Equation attempts to estimate the number of intelligent space-faring species in a galaxy and, by most accounts, comes up with a number noticeably larger than one. The Fermi Paradox says: Okay Mr. Drake… if so… where are all the aliens?
