On top of that, they face massive lawsuits for violating existing IP etc. It's far from a proven business model indeed (heck, OpenAI isn't even profitable yet), and even further as a technology (because it is so inherently unreliable - no matter the model size).
World impact is not how Nobels are won. If that was the case Elon Musk, Jeff Bezos, Zuckerberg and others would all have multiple ones.
I honestly do not see this paper as being in the same magnitude of brilliance as a typical Nobel would be. Not to mention that it barely counts as science (actually it probably does not). Don't get me wrong. It is a huge achievement for both the machine learning research field and for humanity as a whole, but putting along the achievements of Nobel physicists and such feels wrong.
