But ITER was never even promised to be ready to fire up before 2050, and there has never been any intention expressed to generate power with it, commercial or otherwise. The promise was that after ITER work is done, they might be ready to spend $100B-300B on a commercial plant to be completed around 2100.
No commercial power will ever be generated by Tokamak. Its sole reason for still being pursued is as a jobs program for hot-neutron physicists, to maintain a population to draw on for occasional weapons work, although the large dollar amounts involved are a convenient channel to funnel public money to select private pockets.
Of course, by 2100 we will have overwhelmingly better choices available than this massive boondoggle. Even fission is more viable. Even orbital solar is more viable. More likely, terrestrial solar and wind will have long since crushed all competition except, maybe, geothermal.
In the meantime, every cent spent on Tokamak is stolen from work on actually viable ways to counter global climate disruption. Has been for decades.
There is one small boon from Tokamak work. Besides the hot-neutron scam, they are training up a generation of plasma physicists, which will have important, thus far unknown benefits if we don't blow all the opportunities.
