What is this word salad? "Spirit?" Intention? Disarm the "warrior narcissist?"
Good luck - this flies in the face of the entirety of human history.
> "what would it take to turn an AK47 or an AR15 into a water pump?"
As someone who has manufactured these from billet: why would you do this? (hence "word salad") Why does one thing at all relate to the other? Why not just manufacture a pump from the same raw resources? Why not both?
> Those who think weapons are necessary must always take lesser priority than those who invent technology to make the lives of their fellow human beings better.
Did the Allies in WWII not "make the lives of their fellow human beings better" using violence? Why didn't they just ask mean old Hitler: "Hey, be nice! Have a good spirit!"? The world has finite resources, inherently making anything often denies those resources (your time, actual materials, etc.) to other causes. "Better" is subjective.
> There are so many examples of the tool-makers winning harder and at greater scale than the bomb-manufacturer.
These organizations are often one in the same.
> We wouldn't be here now if the balance was the other way
The balance is already the other way regardless of your citation-free assertion. You're using the internet to proliferate this tripe - famously a DARPA invention.
> Imagine if those F35 mounting pylons were used to drop field-portable water-purification systems directly where they are needed most.
Why is a high-performance stealth aircraft required for this? Why does one thing have anything to do with the other? What peaceful purpose does stealth capability serve?
> Imagine if those ships were being used to bring power to the villages that need it most.
No need to imagine, this already happens: https://en.wikipedia.org/wiki/Powership
> Disarm them too.
With what? Words? Precisely how do you non-violently disarm someone who is willing and demonstrated to use violence to prevent you from disarming them? Again, the world's resources are finite, and control of these resources inherently requires violence.
Your ability to spread these "ideas" are rooted in violence: taxation, freedom generally. Freedom isn't free, and the price is paid in blood.
There's a real problem with governments that invade other countries and attack civilians, and we're in a particularly hot time right now. That gives many current examples, though: should Ukraine prioritize manufacturing water pumps? Or do they mostly need weapons to fight back in the war?
I get that folks don't like war. I hate war. I've seen much more evidence that deterrence produces peace more readily than disarmament. On the flip side, more destructive weapons may be used more rarely, but they kill more people when they are used.
I'm not sure what the optimal approach is, but it almost certainly requires nations to arm themselves in case they are attacked. "Provide for the common defense" was not specified idly.
