Name the next most intelligent animal to humans...
Have humans completely and utterly conquered them?
The intelligence explosion already happened and humans were it. Now you're questioning if it's possible with intelligence explosion 2.0?
The intelligence explosion was useful to humans because humans can make more humans and command more resources. An AI can clone itself only on resources that humans make.
