The book responds to most of the "not there yet" concerns. The idea is that if there are 1,000 species aware of even primitive life on a particular planet, chances are at least one of them will be close enough for it to be worth the effort to destroy it. This is because technological development is exponential and you can't predict if/when a planet will produce dangerous technology equal or greater than your own. If you wait, you only increase the risk of being destroyed.
- LatteLazy 5y agoI haven't read the book, does it answer these points: There are only 76 type A stars within 100ly of us (100 light years because we've had powerful radio about that long). So even assuming every star had a civilisation capable of destroying us, that's only 76 of them. Similarly, we've had primative life on earth for millions of years. If a civ exists that can detect primative life and wishes to destroy it, it would have done so by now on earth since the milky way is only about 100k ly across. That's without getting into whether technological development is actually exponential, whether it caps out or how fast it is...
