Adam Ford interviewed me again, this time on the Great Filter:

We have three main sources of info on existential risks (xrisks):

1. Inside View Analysis – where we try to use our best theories to reason about particular causal processes.

2. Earth Track Records – the empirical distribution of related events observed so far on Earth.

3. The Great Filter – inferences from the fact that the universe looks dead everywhere but here.

These sources are roughly equally informative. #2 suggests xrisks are low, even if high enough to deserve much effort to prevent them. I’d say that most variations on #1 suggest the same. However, #3 suggests xrisks could be very high, which should encourage more xrisk-mitigation efforts.

Ironically most xrisk efforts (of which I’m aware) focus on AI-risk, which can’t explain the great filter. Most analysis efforts also focus on #1, less on #2, and almost none on #3.
