Unlike the human brain, computer software can be easily updated and experimented on, which means it can be upgraded and expanded to areas where human brains are weaker. For example, while our vision software is really advanced, our engineering capability is pretty low-grade.
But computers could be optimized for both of those things.
Plus, computers are way better at collective intelligence than we are. Humans have built up a vast collective intelligence over time, beginning with language and the forming of large, dense communities, advancing through the inventions of writing and printing, and now intensified through tools like the internet.
But a worldwide network of AI running a particular program could easily sync with itself, sharing information instantly and working towards a shared goal without the dissenting opinions and motivations that humans often have.
