> We designed and built ITER at such a large size and cost (€20 billion) since high temperature superconducting magnets were not yet available.
This is one of those numbers that only seem big without context. Medium-sized cities spend more than this on interchanges and highway development over shorter timespans than any of the various multi-decade price tags that get thrown around for ITER.
