It's been explained dozens of times in this thread, and I'm going to guess on Twitter and maybe even in person, but he doesn't get it.
Robert. Listen. Science. Evolution. The Future. It's not some pre-destined thing that is meant to happen a certain way according to a script.
Let's use the same logic you've likely used against Christians who complain that what you're doing is against "God's plan". If the plan has an unknown goal, is all encompassing, is unknowable by design, and no-one is told what they are supposed to do as part of that plan, then there's basically no plan at all. We can do nothing else but act according to our own free will. Anyone who claims to know the plan is going to need to do a lot of convincing, and if those same people attempt to change your behavior they could be interfering with God's plan and not realize it.
That's you Bob. The only difference is that your holy book is some 1950s sci-fi you saw when you were 6 and some open boarder communist bullshit you heard 10 years ago.
Evolution and scientific progress is basically adaption and incremental improvement. It has no set goal, direction, or results. Future predictions are nothing more than guesses based on what's happening now, and when we're wrong, we change things to adapt accordingly. ie. The exact opinion you've spouted for for almost 2600 pages. You complain that those "Mayonnaise Ghouls" won't shut down their "Smog Factories" and learn to science, but you won't update your model of the future from the time when those factories were built.
I wonder if this is another thing tied to his mood swings. If Bob wants to comfort of the past when he's depressed, but wants his jet packs and moon wheat when he's manic. Though if that was the case I'd expect a clear split between childhood nostalgia and technological progress at any cost. Instead, Bob's ideas are a strange, nonsensical retro-futurism.
