Inspired by a dialogue in Getting Off the Space Elevator, wherein:
Is "It can’t be done’ a claim in any meaningful sense?
How can one be expected to support a statement to the effect ‘it can’t be done’?
Invariably in debates like this, assumptions are made about technological advances overcoming every barrier; is it accpetable to make these assumptions? is it up to the “it can’t be done” side to prove that such technological advances aren’t possible?
PS…I don’t want this thread to turn into another space elevator debate, thanks.
