Lu100: That the reason why IBM's chip factories with manufacturing process that uses 8-inch silicon wafers are for sale. If it takes too long, they won’t be for sale anymore but for free!

Good point, lu100! And POET might also bring new new life to older fabs which are restricted to 40 nm or so and cannot cope with with most recent silicon developments. POET at 40 nm should perform much better than silicon at 14 nm, let alone energy consumption. Big cost advantage!
