Re: At what point
At what point is it cheaper and simpler to build several dozen jet engines, each to a one-off specification, rather than build a simulation of just one and tweak its parameters?
"There, fixed that for you" as they say.
But yes, this beastie would be fairly close to that point. I assume it can also be used for other things, and I also assume that its builders have learned a fair bit about architecture and so the next one will be cheaper.
