That's fine but to act like new small scale experiments and designs obsolete technology that has never before been developed at scale is silly and frankly runs contrary to how technological and scientific progress are made. I'll never understand the biases of theorists. They act as if all theory isn't deeply indebted to practical learnings. You don't commit to a project like ITER because you believe it will turn out a cutting edge solution to a problem. You do so because you believe that whatever happens, in the end you will harvest many learnings that are widely useful.
