>O’Neill cylinders are potentially feasible within a century or two
Is there anything fundamentally holding us back from building one right now? I mean there's the obvious problem that nobody has a good reason to build one, and only a hand full of entities have the funding to do so. But the engineering challenges seem to be on the level of building LHC or ITER: not nessesarily easy, but very doable.
