good point

all just science fiction tho. And since it is hundreds of years in the future, it's hard to get us humans of the present to spend trillion on it. Which means it will take even longer for our future descendents. Maybe if climate change is real it will force people to speed it up and work on it for the future humans but I doubt it. And this is the great filter. We'll be extinct, that's more likely than traveling to other planets. I think AI being the only thing to survive is more likely.
