Congratulations India! The more countries that have independent space programmes the better.
the fallout of this is spacewar. And billions killed. it is a new frontier for sure. And I am not looking forward to it.
Spacewar is a possible future, and I will not deny that. But one could apply the same pessimistic view to not going to space as well.
"The fallout of not going to space is resource wars. Billions killed, their bodies harvested in order to extract water and nutrients".
However, it is not "unnecessarily" pessimistic. There are actual fiction books, congressional hearings, military strategies in motion that play out such outcomes. The US has a space force command. And missiles to space have been sent to knock out targets.
Calling it a fallout, implies when all things fail and hell breaks loose.
