Let humans have at least some ambitions...
We gave up on colonizing space for almost 50 years.Humanity needs a common goal, and science could be at least a bit motivating.
@cjd
So, what ambition for humans can you offer? If discovering science ain't enough?

Then how can we judge whether "it is worth it"?
We're speaking about costs in the range of the GDP of a small country and the energy consumption of a medium one - there has to be a significant advantage o this. "Muh, knowledge" probably isn't enough.
