You write "and sci-fi authors would come up with the same ideas" and list some examples of technologies.

SF authors did not come up with any of the technologies you listed. SF authors are primarily story tellers who incorporate the ideas of others to tell the story they want to tell.

That's not to say they don't come up with new ideas. "John Carter of Barsoom", Captain in the Virginia Army of the Confederacy is an idea too.

Do you think a black science fiction author of the early 1910s would write the same story? I don't.

If world history had been completely different, why would we get another Lost Cause hero, rather than "John Carter of Barsoom", freed slave from Virginia, who found the portal while working as a cowboy in the US West?

Your focus on just the inventions clearly rejects the following observation from the article:

"SF is a profoundly ideological genre—it’s about much more than new gadgets or inventions. Canadian science-fiction novelist and futurist Karl Schroeder has told me that “every technology comes with an implied political agenda.” And the tech plutocracy seems intent on imposing its agenda on our planet’s eight billion inhabitants."

You want to focus on the idea "Electric Rifle" when the bigger part of the story is "invent something to make a lot of money", in this case by killing elephants for their ivory, with little consideration for the land or property rights of the local inhabitants.

(L. Neil Smith gives an example of clearly ideological SF - imagine libertarianism works, that it results in faster economic development and more freedom, and there's an inter-dimensional war between libertarians and (evil) anti-libertarians.)

These fans of Swift, and of John Carter, and of pulps in general, wanted more of this, and authors and publishers were more than willing to provide it. Some of these fans became the next generation of authors.

SF was not leading the way in understanding non-white, non-male, non-hetero ideas, even though NONE of the ideas you mention are gender or race specific.

Instead, you need to look to outsiders, like James Tiptree Jr., or Cordwainer Smith, to see what alternate SF might look like. In Smith's universe, humans aren't able to travel in space until Haber develops a technique to shut down all senses but sight. Only these habermen were able to withstand the cold stillness of space. Even once the great planoformers were invented, which used life itself to buffer humans from space, human ships couldn't survive against creatures that lived in the depths of space, that looked to humans like great dragons, and attacked faster than humans could respond. Only with luck did we discover that cats see them as large rats, and via a telepathic link with their human could direct the defenses. The universe still contain indescribable dangers, like the Douglas-Ouyang planets, which must be guarded against.

In Smith's universe, human cultures tend towards long-term stability not expansive growth; on Earth maintained for tens of thousands of years by the Instrumentality striving to keep man man, but even on Norstrilia there's been 150 generations of the same family on the same farm - and these people live for hundreds of years due to stroon, a life extending drug extracted from a sheep infection, though after 800 years or so your brain no longer really works.

> Space colonization has none of the problematic baggage of historical colonization, by default.

No? Who gets to be the colonizers? Who pays for it? Who gets left behind? Why are they starting a colony? Who runs the colony? Will there be a class system?

The fact that it's in space doesn't change any of the historic baggage attached with colonialism.

> which he associates with this colonialist and conservative history

But they do. These billionaires have a view of space conquest clearly based in mid-20th century views back when people thought it was simple.

We don't know how to make a self-sustaining colony in space. We don't even know how to make a self-sustaining independent ecosphere on Earth, which is much easier. So any colony is going to require continuous resupply. Who will pay for that, and why?

(Back 50 years ago that was wished away with terms like "hydroponics" and "atomic energy".)

Even harder is to colonize space with a self-sustaining population. We know just being in space is tough on human bodies. I don't think it's at all ethical to experiment with pregnancy in space and giving birth/raising children there.

So, now we have a space colony on Mars. How many people does it need to be self-sustaining, so we don't "have all of our eggs in one basket"? Besides food and maintenance, we need people who can raise children, and educate those children in all the technology required. If there are computers then they need a chip fabber, and a way to make silicon, and all sorts of other technology.

This web of technology needs, what, a million people to have enough with the right sort of expertise and with enough redundancy?

None of this was really discussed in mid-20th century SF, nor by these space billionaires and their supporters. That's because it's harder to write an entertaining story based on the real life limitations we know. Magic up a warp drive and your heroes can visit the stars in days rather than multiple lifetimes from now.

> Artificial intelligence and life extension does not have the baggage of eugenics and race theory

AI does have the baggage of labor rights, which in turn goes back to the early Industrial Age and the Luddites. AI use was one of the reasons for the recent Hollywood strikes.

Who gets life extension? Those who can afford it? Those in rich countries? Those who are awarded it by a panel, and how to they decide? Random draw?

You'll notice that several of these are proxies for wealth and race, and do recall how "IQ tests" and "literacy tests" were long used as a history for racial and economic discrimination.

This is also very much like the baggage concerning who gets health care.

> Virtual reality does not have the baggage of control and suppression.

I still don't get the hype of VR, but given how companies want to surveil and control their employees working from home, what would it be life if they could surveil the employee's entire 3D experience?

> They are all fundamental economic ideas independent of our world and it is our decision to associate them with the stories of certain sci-fi authors or not.

The problem is "the billionaires behind the steering wheel have mistaken cautionary tales and entertainments for a road map", not that those ideas are associated with SF stories.
