Nope not marketing. I researched this topic myself. I'm not aware that Nvidia mentioned this.
But hey it seems I can't convince you of my enthusiasm regarding ai. It's fine I still will play around with it often and looking forward to it's progress.
Regarding your researcher: NotebookLM is great and you might need to invest a few hundred bucks to really try out more.
Your enthusiasm for AI is just more hype noise as far as I'm concerned. You say you've "done research" but then don't link it for anyone to look into, adding to the hype. Brain compute performance is not a well-understood topic so saying some product approaches it is pure marketing hype. It's akin to saying the brain is a neural net.

We will see anyway we're it's going
