If its like the other projects, it may never generate a single kWh when it gets cancelled.

Also, it will be much too late to avoid massive climate change so its a bit mute. And that's assuming we also cut all our other emissions and every other country on earth cuts theirs...

Plus "no matter what the cost" is a pretty weird attitude if you don't mind me saying. If we can save more carbon by spending the same money elsewhere, shouldn't we do that instead?
