How did a computer scientist such as Geoffrey Hinton manage to win a Nobel Prize in physics when computer science already has its own Nobel Prize equivalent in the Turing Awards?

You can have your cake and eat it too

"Hey guys, AI is pretty big so let's centre our prizes on it this year. We can get some attention, and it's all about advertising, at the end of the day, isn't it?"

In December 1973, when Kissinger was awarded the Nobel Peace Prize, comedian Tom Lehrer dropped his mic and stamped on it—satire had just died.

Why have feminists not demanded that females be required to register with the selective service? Are female lives more precious than male lives?

Whatever.

Whatever.

"Naah, Linnainmaa is a Finn. Can't give it to a bloody Finnish mathematician. Let's go for drinks. Brännvin anyone?"

Fortunately, we are privy to the discussion that led up to this:

… then anything is possible. There’s no rule that a Nobel Prize has to make sense.^*

"Good idea, but how can we wangle something that says 'Physics'?"

Why wait any longer for the one you love?

In awarding prizes, the Nobel Committees often seem only marginally more competent than MTG is at explaining meteorology. And if they can give a literature prize for lyrics like:

"Good point, I'm sure we can swing it. And let's tack on Hopfield while we're about it."

(Bob Dylan, Nobel Prize for Literature, 2016)

"Didn't he do something with Boltzmann in it? That sounds physics-y. RBMs and stuff, eh?"

They then move on to selectively provide their own version of history. But hey, it’s OK. They wanted controversy, didn’t they? Whatever.

[Younger voice] "But wait a minute, Ising-Lenz goes back to the 1920's. And didn't Hinton plagiarise rather a lot? He also didn't invent modern backprop, did he, that's Linnainmaa? And Amari preceded Hopfield, too. That's not a good look."

[The basic structure of artificial neural networks] has close similarities with spin models in statistical physics applied to magnetism or alloy theory. This year’s Nobel Prize in Physics recognizes research exploiting this connection to make breakthrough methodological advances in the field of ANN.

"Where can we shoehorn it in? Chemistry is easy 'cos AlphaFold; but what about physics? A bit more challenging, right?"
