Off topic, but does the sentence structure of STATEMENT-QUESTION MARK have a name? It's pretty annoying in my opinion. Why not write "IS the von Neumann bottleneck impeding AI computing?" instead?

As an Italian, it translates as we actually state questions, so it feels natural to me :)

But you're right, I think it's not even grammarly correct.

Anyway, I'd like always to remember this about headlines as a question: https://en.wikipedia.org/wiki/Betteridge's_law_of_headlines
