is this really a wafer sized chip? Because that sounds…difficult and expensive…and very difficult. A manufacturing or packaging defect is going to be very expensive when you have to throw the entire wafer away.

The trick would be to design the chip such that every part is redundant and can be disabled if there's a defect. Tricky, but certainly not impossible.

It's still going to be a massively expensive chip, but it should be extremely rare that you actually have to discard an entire wafer once the early production issues are worked out.

The real key for adoption, aside from price, will be just how flexible the programming model is and how difficult it is to put into production.
