Ah, yeah that is totally valid. My thinking is not exactly that fusion power will be cheaper than fission any time soon, but that the technology has the potential to deliver safer power, and as important as wind and solar are to our transition over the next few decades, I believe that fusion has the potential to deliver much higher levels of power than wind and solar, allowing for new uses for electricity previously considered impractical. I wonder what kind of new manufacturing processes we can come up with if we have enough power to deliver huge amounts of process heat, for example.

I agree with you that in a practical sense fusion power will not be economical in the next 50 years, but then solar power was not economical for most of my life either. I am excited for the technology to get to the point where at the very least it is producing power, as this will stimulate more investment in lowering the costs, and has been such a dream for longer than I have been alive.
