I like this image even more than the one in the tweet:

It helps my layman's eyes clearly relate the trajectories of the various developmental processes of each approach. I wonder why SPARC and ITER are the only projected ones. Do the other reactors being built not have estimated yields? My favourite has long been the wendelstein, because of they way it looks and how it feels like its pathway to success might be software based. I like the way Tokamak Energy markets itself, and would have loved to see the ST25 and the ST40 in that image, but maybe they're not complete enough projects to be on there?
