Hope and Worry are activities we undertake in the Present when thinking about the Future. To many philosophies, these activities are futile and ultimately damaging to our well being.
Well.. I Hope that sentient life on this planet is short lived. I Worry that I might be wrong.

Life has been going on for billions of years, already, so, it's a little too late for hoping it is short lived. It could go on another few billion years (not Homo sapiens, but, other species).
