This is exciting, but even when they go into production, this will no doubt only
be affordable by major observatories, not amateur astronomers. Likely we're
talking six figures here.

Of course, perhaps eventually inexpensive manufacturing techniques will be
found, such as SOI where the insulating substrate can be heated enough to make
it malleable without disturbing the delicate microcircuitry on its surface.
Since a sphere is not a reducible surface, though, the interconnects will have
to survive stretching.
