Billions not trillions.

"If humans wanted to travel to extra-solar planets, then they could do it. It would take a lot of work- not millions of man hours, but trillions of man hours."


Trillions would be like every single person on Earth working for a year on that single project.
I think billions of man hours is a more likely estimate.
