Specifically, I would love to see a better argument for it being ahead of Helion (if it is actually ahead, which would be a surprise and a major update for me).
I agree with Jeffrey Heninger’s response to your comment. Here is a (somewhat polemical) video which illustrates the challenges for Helion’s unusual D-He3 approach compared to the standard D-T approach which CFS follows. It illustrates some of Jeffrey’s points and makes other claims like Helion’s current operational poc reactor Trenta being far from adequate for scaling to a productive reactor when considering safety and regulatory demands (though I haven’t looked into whether CFS might be affected by this just the same).
