Compared to some of the more woo folks, he at least, in as far as I’ve seen, doesn’t just make up random stuff. Following a through line of hard cope futurism gets normal people engaged. That’s the difference between Star Trek and Three Body Problem. Star Trek retcons plot devices into vague science slop. Hard science scifi extrapolates the world based on what we know. What is the actual harm in taking something amazing and using that as the base from which to discuss practical applications in the future? That’s still science fiction because it’s simply not real life.

I really don’t understand the hostility towards someone genuinely qualified to make a basic statement on something as poorly understood as dark matter being upsetting to you.
