AI is frequently used to discover things that would take laborious amounts of time for humans to do. For example, AI can be used to find the optimal configuration for a mother-board layout or identify best fit parameters for a financial model. Frequently, the AI can do a better job at a task and do it quicker than a human. Therefore, in many applications, the AI is already more intelligent than the creator at specific tasks.
Here are just a few things that AI can already do better than humans:
- Playing Chess
- Playing Jeopardy
- Detecting Cancer
To argue against the possibility of a super-intelligent AI is somewhat of a mute point since it has already been proven.
