You're assuming that AI will compete with humans, because that's what similar sentient biological entities do. However, AI won't need to compete with humanity if we don't program it to compete.
If we want AI, we will have to build something that only embodies the part of us that makes us human; not the animal part that all living things need. AI won't need to be biologically programmed, since it won't be alive by any biologist's standard. It will be silicon based, not carbon. There will be no need for AI to wipe out humans unless we give it that need. Humans need to wipe out humans because we're competing for resources. AI won't need to compete with us.
The only way I see AI turning on us is if we fail in creating AI, and instead just create man inside a machine.
