Almost every technology can be used to wage war. But not all war activities are evil. I am happy that the Ukrainians can use Starlink to defend themselves against a brutal aggressor and preserve sovereignty of their country.

"The difference between Starship and a missile designed to kill people is a simple swapping of the payload."

If you insist on this worldview, you will always be miserable around every technological development out there. Just imagine what can be done with mRNA or maybe 3D printing.

"I am not enthusiastic about notorious individuals having the will and capability to mass-weaponize space."

I am pretty sure that militarization of space will be a decision of governments, not Musk himself. He is not rich enough to be able to build an actual orbital army and not get arrested.

Unless by a "notorious individual" you mean Trump or Xi... in which case, there isn't much new under the sun, because governments have weaponized space since the very beginning.

What I feel is positive is the civilian use of the technology. The military use will always be there, but the civilian use needs better and cheaper tech, which is what Starship is. Some medications could be produced in the orbit for example, and with enough launch capacity, they could be produced for the entire planet at once.
