The potential is hard to ignore, but that doesn't mean the potential will ever be achieved. This (like crypto currency) is the realm of vapourware I am afraid. Always just around the corner. :(
What's sort of my point: we've had big projects that would totally definitely work this time every few years since the 90s. Will ITER work? Maybe. Would it be the first to fail (or even the 10th) if it doesn't? No. Per your own link there are literally 100s of other "reactors".
