> if A=B and A=C, then A=C

Technically true, but you might still want to double check your logic.

Not all of the work. For example, it doesn't account for the fact that Demis Hassabis, as head of DeepMind, undoubtedly recruited many of the co-authors to participate in this effort, which is worth something when it comes to the final output.

To recruit isn't scientific work.

I didn't realize the Nobel specified that the only work which mattered was that of the "scientific" variety.

What will the paper do with the prize money?
