OpenAI have said they will not claim the $1 million prize.
And certainly mathematicians will now be pondering what all of this means for the future of their subject.
Sam, thanks very much for your time.
Thanks for having me.
So I think everyone will be familiar with the fact that a bad night's sleep can lead to a drop in cognitive abilities, a feeling of stress and just general moodiness the following day.
Sam Weichle is a science correspondent for The Economist.
If this persists, then chronic sleep deprivation can also be linked to persistent cognitive decline, psychiatric disorders, and even an early death.
But what maybe less people have heard about is that too much sleep can also be bad for you.
So scientists call this the U-shaped relationship between health and sleep duration.
Both too little sleep and too much can lead to increased health risks.
So what is too little and is too much?
What's the ideal amount?
Well, there were two massive studies in 2015 that tried to address this question.
In both of these, they assembled big panels of sleep experts to assess the literature on the topic.
One, which was published by Sleep Health, found that those aged between 18 and 64 should aim for 7 to 9 hours, and then those over 65 should aim for around 7 to 8 hours.
The second study, which was published in the journal Sleep, found that around 7 hours was the best number, but noted that there is uncertainty about the negative effects linked to sleeping for too long, particularly over 9 hours.
That's true, yeah.
And one recent nature study published in May tried to look at a more fine-grained picture of how sleep duration affects parts of the body.
So they use this concept of biological clocks.
These are a way of measuring how different parts of the body are aging relative to a person's chronological age.
