Imagine an AGI (Artificial General Intelligence) that could perform any task a human can do on a computer, but at a much faster pace. This AGI could create an operating system, produce a movie better than anything you've ever seen, and much more, all while being limited to SFW (Safe For Work) content. What are the first things you would ask it to do?
I think we're pretty far from the peak understanding of almost everything. There are so many discoveries still to be made.
Based on what? Sure, I'm guessing we're just starting with planetary science and cosmology, but power generation has been explored to death and we're still using the same basic alternator design as Tesla was.
