Makes me think the same. I personally believe that no, the concept in the sense that "anything can change and could theoretically happen" doesn't exist, but... I also believe it doesn't really matter either. If there is free will, then anything can happen, if there is no free will, then not anything can happen and it is determined, but since we currently can't predict the future and determine what's going to happen, both situations have the exact same outcomes.

For me, most of these philosophical questions that are (currently) not definitively answerable I liked to ponder for a bit, but dismiss relatively quickly. I don't really care if there is a free will or not, if there is any meaning to anything or not, basically whatever. What I care about is the current situation as far as I can discern it, and my actions that I want to take in the current moment based on that. My biology determines that and I just let it happen.
