Existential risk includes more than extinction, it could also mean society collapses and takes 100 years to recover to current level, or 1000, or 10,000, or _never_ recovers. Maybe some societies collapse but others just turn into deserts. Maybe there is a recovery, but we'll never have the global trade networks of today, maybe we'll never send a man to Mars. It might mean 90% of the population is lost. I've said nothing about the probability of any of that, but it goes up the slower we act.
