Nuclear technology can be used for non-harmful things. Even nuclear bombs can be used for non-harmful things--see, for example, the Orion project.
> These tools are oriented by their very nature to replace human labor
So is a plow. So is a factory. So is a car. So is a computer. ("Computer" used to be a description of a job done by humans.) The whole point of technology is to reduce the amount of human drudge work that is required to create wealth.
> in the context of our economic system has a direct and unbreakable relationship to a reduction in the well being of the humans it replaces
All of the technologies I listed above increased the well being of humans, including those they replaced. If we're anxious that that might not happen under "our economic system", we need to look at what has changed from then to now.
In a free market, the natural response to the emergence of a technology that reduces the need for human labor in a particular area is for humans to shift to other occupations. That is what happened in response to the emergence of all of the technologies I listed above.
If that does not happen, it is because the market is not free, and the most likely reason for that is government regulation, and the most likely reason for the government regulation is regulatory capture, i.e., some rich people bought regulations that favored them from the government, in order to protect themselves from free market competition.
2. Your outlook on the societal impact of technology is contradicted by reality. The historical result of better tech always meant increased jobs and well-being. Today is the best time in human history to be alive by virtually every metric.
3. AI has been such a massive boon to humanity and your everyday existence for years that questioning its public utility is frankly bewildering.
2. This is outdated, life is NOT better now than at any other time. Life expectancy is going down in the US, there is vastly more economic inequality now than there was in the 60s, people broadly report much worse job satisfaction than they did in previous generations. The only metric you can really point to about now being better than the 90s is absolute poverty going down. Which is great, but those advancements are actually quite shallow on a per-person basis and are matched by declines in relative wealth for the middle 80% of people.
3. ??? What kind of AI are you talking about? LLMs have only been interesting to the public for about a year now
This is a vastly overinflated claim about AI.
Increased inequality doesn't imply the absolute level of welfare of anyone has decreased, I don't think you should include it in your list. If my life is 2x better than in the 60s, the fact that there are people out there with 100x better lives doesn't mean my life is worse.
It's most likely the main reason there's no direct world wars between super powers.
