You're going to have to elaborate on that, because AFAIK humanity has not solved intelligence to the point that we can say it is entirely nurture. That makes it reasonable to assume that it is part nature, which means that yes. It is genetically better than others' brains. And there's nothing wrong with that.

You don't believe success is a combination of nature and nurture?

with ladders/bridges and walls/moats i am talking about the existing material reality that has one class (the propertied class) creating unnecessary artificial scarcity (on non-scarce material, i.e. using the intellectual property system) which stops the organic spread of technology and knowledge overall, as it's following the profit motive of capitalism. this article is from a socialist magazine, so it's common to refer to systemic black boxing and alienating/obscuring technology as 'gatekeeping'/'rent-seeking' (creating walls with unaffordable gates (for 99.999% of us)).
