If you open any book by scientist and historian Jared Diamond, to any page, you will find something fascinating, like this from page 291 of Guns, Germs and Steel:
"In 1905, motor vehicles were still expensive, unreliable toys for the rich. Pubic contentment with horses and railroads remained high until World War I, when the military concluded that it really did need trucks. Intensive postwar lobbying by truck manufacturers and armies finally convinced the public of its own needs and enabled trucks to begin to supplant horse-drawn wagons in industrialized countries. Even in the largest American cities, the changeover took 50 years."
This passage should be a revelation to anyone born after World War II. No one alive today remembers a time when the public did not believe in the necessity of an unsustainable culture of cars and trucks, bringing constant noise, pollution, speed for its own sake, vast injury and death. We don't remember this skepticism about internal-combustion based personal vehicles because the memory has been aggressively erased by various forms of propaganda, such as advertising and movies.
In World War II, Diamond further discusses, the US spent $20 billion developing an atomic bomb, propelled by a perceived necessity of beating Hitler to it (later it was clear that the NAZI regime had little chance of developing the bomb before its defeat).
Diamond calls these modern practices a reversal of the idea that "necessity is the mother of invention;" rather they show that "invention can be the mother of necessity."
Diamond's examples highlight the role that war plays in creating necessity, something we should ponder now as rumblings of war increase. How might coming conflagrations enable introduction of new technologies? At first glance it does not appear that interested parties need war to create necessity for their products. The general public is already enamored with computers, the Internet, cell phones, social media, AI and robots- already believing that we need these things. But most people do not believe that they need to be displaced by machines from anything you could call "employment." AI, even in its early stages, appears potentially able to perform any human job. Many people would prefer to keep their jobs, using the income to purchase AI's products. War could overrule that preference. For instance, if war creates a shortage of doctors, people who are averse to a robotic doctor will go to one if that is the only option. A generation later no one will remember a need for human doctors. It's hard to think of a profession that is not susceptible to such "automation," as we used to call it.
.
When the perceived necessity of AI combines with the perceived necessity of genetic engineering, we will face an atom bomb of evolution that will compress millions of years of gradual change into one or two generations. It will be explosive enough that current humanity will become as distant a memory as pre-agricultural humanity.
You would not know we face such a future from public commentary. For instance, no element of this topic was discussed or even indirectly referenced in the recent presidential debate between Donald Trump and Joe Biden (public commentary was concerned only with the ups and downs of gerontocracy) or in Trump's later debate with Kamal Harris.
How do we transfer concern for our species' future from the bedrooms of sci-fi nerds to a more public awareness?
[Update, 12/14/24: Trump's public commentary in the weeks since his second presidential victory continues to avoid reference to the end of our species as we know it. He talks about the economy, immigration, unrest and war overseas (with questionable rationality), which are important areas for a president to address. But a president should also address a scientific/cultural/philosphical/moral issue like the end of what we recognize as our civilization and physical selves. The clear outlines of our supercharged evolution will probably emerge during Trump's second term, but, unless something changes in our politics, it is unlikely to be on his radar.]
