The tech-using superheroes all have 'tech bro' as their backstory, but this has almost nothing to do with the plot or their on-screen actions. They are occasionally shown doing product launches etc. because that it a thing that tech millionaires do, but all of the on-screen action is defending against change, not causing it. And the 'tech going wrong or being exploited' outcome is approximately 100% of the portrayal of events, there is almost no screen time on an invention making the world better.
It may not be as memetically optimized for the modern LW audience as ingroup-written rationalfic, but I recommend reading A Connecticut Yankee in King Arthur’s Court. It is (one of?) the first-ever 'engineer uses technical knowledge to fix a primitive society and instill modern values' stories.
These quotes show how anti-progress and reactionary Tolkien was. He hated machines, he hated housing construction, he hated innovation. He would condemn humanity to be tenant farmers ruled by a warrior aristocracy at a medieval tech level, forever. If you want to live in Tolkien's utopia, move to Zambia.
Basically, Tolkien is very much like the Unabomber. He saw real problems, but his proposed solutions are destructive. He was a master of using the bouba–kiki effect to incept his worldview in the minds of millions, so he did far more to stop progress than the Unabomber ever did. He bears significant responsibility for the productivity slowdown, and for your rent being too damn high.
