[edit] They did mention the error/bad core handling briefly, as Druidsbane correctly points out [/edit]

Obviously not much specific detail at this stage, but it strikes me as odd that there's no points from Cerebras that seem to address the obvious concern with fabrication errors - I'd always understood that by having many small chips that mitigated costs, because one single chip could be toast but you'd still have a substantial number of unaffected ones to use.

Unless they've got some special solution up their sleeves, it seems like one error would knock out the whole chip.

Also, by needing it to be square, won't they fail to utilise the sections between the edge of the square and the edge of the wafer's circular edge?

The article mentions that they are building extra circuitry to circumvent any bad cores. Not much detail but at least they have addressed this.

Sorry you're completely right, I must've missed that whole paragraph.
