There's no debate to be had most of the time. Something about this particular topic makes people so prone to decide they're right first, then debate as if making the smallest concession means defeat.

Any discussion on the basis of "X will solve Y" or "X will most likely NOT solve Y" predictably spirals on and on because the parties chose hypothetical claims that can't be falsified so it's easier to play with semantics and pretend the other doesn't get it yet.
