If someone doesn't accept an extraordinary claim without evidence, that doesn't mean they are making an extraordinary claim.
a) 10% existential risk
b) 0% existential risk
* The "predictable power of AI" is very advanced predictive text. What a lot you can do with that, and there are clear limits.
* AI has no intent. The greedheads who find themselves in these positions of power have clear intent (often but not always bordering on and actively becoming misanthropic) put their intentions on AI - hence to doom mongering
* Who will starve with the failure of agriculture? A few, a lot, but not everybody. We are good at this - have been doing it a lot longer than computing or science
So yes, it very obviously is an extraordinary claim to say there is 0% existential risk.
I have a bridge to sell to anyone who believes a big claim without evidence.
Likewise, one can quite reasonably say there is no credible existential, Hollywood-style threat from AI in the foreseeable future while recognizing far lower-stakes, yet important risks that need to be addressed.
Stating that the probability is zero when we simply don't know what the probabilities are does seem like an extraordinary claim.
Imagine how reassuring it would be to people if we had evidence that there's no existential risk?
He prevented a catastrophe, but not annihilation. We were not at risk of that in 1962 and even if he had decided to go with the others, more decisions would have been needed (not just his) to fully escalate to full scale nuclear war. I will reiterate: We have never been one decision away from full scale nuclear war.
But in case you don't understand why, it's because no one person can actually launch all the missiles. And considering the two major arsenals (US and USSR), there has never been a time when two people could make the same decision (launch) and actually launch all the missiles. The orders still have to go out and acted on, many decisions have to be made in order to have full scale nuclear war and come close to annihilation.
Nuclear, Overpopulation, Peak Oil, Y2K Bug, Global Warming.
No, we aren't going extinct in the next 10 years.
