Many people are understandably skeptical of dramatic claims about existential risk or AI takeover (let alone specific probability estimates) for various reasons. But delaying action until we settle disagreements over the scope and severity of AI risks under high uncertainty seems counterproductive as long as the ~ same initial mitigation measures are justified under competing risk assessments. If you notice early signs of a leaky pipe in your home, you can have a debate about whether it’s likely to damage a wall, ruin a room, or flood the whole house. You can also debate what caused it: maybe the contractor did a shoddy job installing the sink, maybe the pipes are being pushed past their limits. But you should probably start by containing the leak and calling a plumber to investigate (substitute a swarm of termites for the leak if you prefer, and add speculation about the "goals" of the swarm). This doesn't settle which repairs you should do, who should pay for them, who should take the blame, etc., but at least it's a step toward preventing further damage.
