Imagining what I might ask Sam Harris about his belief in Determinism

I get how you can stick with determinism and still hold people accountable purely as a logical way to maintain society but how do you hold yourself responsible if you truly believe that you are not the author of your behavior and thoughts? When you accomplish a goal how do you celebrate when there is no "one" to celebrate? When you make a mistake who do you blame if you truly believe that there is no "self". Do you go to bed at night attempting deeply to convince yourself that the thoughts in your head are completely out of your control? Isn't meditating an example of how thoughts influence behavior? And mediating, in turn, influences thoughts and behaviors but who decided to start meditating? If thoughts cannot affect behavior then why attempt to control them, understand them or otherwise think of them in any positive regard. They are just the whisperings of neurological fireworks. Just a show to keep some observer busy? When you sit to write, isn't that an example of thoughts directly influencing outward behavior? Then why is it so hard to imagine that thoughts can also affect the world? I guess Sam Harris doesn't think that thoughts cannot affect the world, just that there are no authors to thoughts. That they are outcomes of prior causes and effects and no more under our control than a rock falling down a mountain can control how it falls. But people can control how they fall? They build things and experiment and communicate. How is that not an example of the massive difference between people and everything else? If the universe is simply a series of perfectly predictable causes and effects then humans are no different so just because humans do things differently doesn't make them special or different. If the universe is fundamentally unpredictable due to the uncertainty inherent in physics doesn't that mean that determinism can't be true? Or at least that there is some room for chaos and uncertainty. Which might be where consciousness and free will preside. IDK. Maybe free will is a non-absolute term that simply refers to the perception that a conscious effort has been made toward realizing a goal. Or it is the ability to recognize the difference between the current state and an ideal state and working toward bridging that gap? Maybe it is just another name for taking responsibility even when we know we don't control everything.
