My best guess for that is actually about one in three this century. If we carry on mostly ignoring these risks with humanity’s escalating power during the century and some of these threats being very serious. But I think that there’s a good chance that we will rise to these challenges and do something about them. So you could think of my overall estimate as being something like Russian roulette, but my initial business as usual estimate being there’s something like two bullets in the chamber of the gun, but then we’ll probably remove one and that if we really got our act together, we could basically remove both of them.

This may have been specifically if the transition happens in the net 100 years; it's possible Ord would estimate we'd have a different chance if this transition happened at a later time.
""Basically, you can look at my [estimate that the existential risk from AI in the next 100 years is] 10% as, there’s about a 50% chance that we create something that’s more intelligent than humanity this century. And then there’s only an 80% chance that we manage to survive that transition, being in charge of our future. If you put that together, you get a 10% chance that’s the time where we lost control of the future in a negative way.

[For people who would disagree, a question] is why would they think that we have much higher than an 80% chance of surviving this ‘passing this baton to these other entities’, but still retaining control of our future or making sure that they build a future that is excellent, surpassingly good by our own perspective? I think that the very people who are working on trying to actually make sure that artificial intelligence would be aligned with our values are finding it extremely difficult. They’re not that hopeful about it.

If you put that together, you get a 10% chance that’s the time where we lost control of the future in a negative way.

Toby Ord: With that number, I’ve spent a lot of time thinking about this. Actually, my first degree was in computer science, and I’ve been involved in artificial intelligence for a long time, although it’s not what I did my PhD on. But, if you ask the typical AI expert’s view of the chance that we develop smarter than human AGI, artificial general intelligence, this century is about 50%. If you survey the public, which has been done, it’s about 50%. So, my 50% is both based on the information I know actually about what’s going on in AI, and also is in line with all of the relevant outside views.
