I made/make no claim about the relative moral merits of capitalism or a hierarchal society at all. However you only need to look closely at your stated claim to see why Conway's Law is relevant here: your claim about "technology" rely on our concept of money / funding staying the same. Given that our concept of money has been evolving non-stop over the past centuries it seems unlikely that it won't further evolve.

I'm not saying that your claim is wrong, rather the opposite I believe it's holds true in the present. Computer Information Systems are reliant on larger economic forces. In many cases centralized systems are not better on a purely technical basis, but rather are better at attracting capital. However there are undoubtably systems of human organization and resource management that would change the fundamentals assumptions behind this.
