How would AI help achieve commercial fusion? You first need to identify the blockers. These almost all entirely boil down to "how do we precision machine large pieces of hard metal?", "how do we assemble facilities with untold process channels?", "how do we capture neutrons without making a prohibitively massive machine?", and "how do we make metal that doesn't melt?".

Now, AI might have a chance at supercharging material research and making miracle materials that help address the blanket and first wall challenges, but honestly those are roadblocks we're not even running into yet. AI can not and will not fix issues related to organizing labor and supply chains and suddenly make megaprojects have a 100% success rate for on-time and on-budget. It's just not going to happen.

So are these problems intractable? Of course not. It's just not what the chatbot is well suited for. Anyone saying otherwise is selling something.

This is the science fiction fan's version of hopes and prayers.
