> Yes, it's obvious that you can fit more transistors on a "chip" if you make the chip be much, much larger than what we ordinarily think of as a chip.
Without defending the article, it is however the case that simply scaling a chip size has nontrivial problems. For example, Will the piece of silicon warp or shatter if one side happens to get hotter than the other?
Possibly. Wafer scale integration has been investigated before though and there were even a couple of attempts at commercial products; it's not a brand new technology. Nevertheless, it might be interesting to examine Cerebras' patents to see if anything of significance relating to WSI is there.
