That’s pretty easily verified by a reasonably competent chip engineer and a microscope, if its 16 and they need to stay on shore only, they could be a little closer in terms of time than I speculated. SMIC at 7nm is reportedly stable; not sure about yields though.

I think if I were in charge I’d probably do a final architecture spin at 16, and then shrink that one to 7 or 5 if I could get it.
