If we lower the bar on papers getting published even further it'd be on the floor. Even with a simple physics argument you can immediately disprove the claim. Human brains have a known amount of compute (as in, we are at most an order of magnitude or two off) within a specific volume. We are already capable of that amount of compute, we just don't have a way to use that compete for AGI yet (and THAT may be hard or impossible but it's certainly not energy resource constrained). We also know the abilities this paper claims are not possible to achieve can be achieved by pretty much every human being within years of being born.

How they managed to massage white supremacy and sexism into this is...well...wow.
