Especially considering that nowadays 180nm is accessible (if necessary, via double-patterning/immersion 405nm to please the DLP's aluminium mirrors) from maskless steppers, which can improve turn-around times by eliminating shared-mask aggregation delays and allows for cheap experimentation (no more minimum order quantity). This is even more significant when one remembers that maskless steppers already have to do stitching for everything significantly more complex than an opamp, and the per-area price scales up to full monolithic wafers without the tiling constrainst Cerebras has to adhere to.
