"we will either destroy ourselves, or we will evolve ourselves"

I agree with you 100%.
based on what I can see from the scientific predictions, there is a time coming when we will face a dreadful climax - which should lead to the either/or outcome in your quote. that step in our evolution is going to be a very painful one. but it is outside of my lifetime, though possibly not outside of the lifetime of our grandchildren.
