Probably the limiting factor is one needs to make sure the customers of chips stay viable. I mean, one hopes the shortage will eventually be over and foundries will want to make sure they didn't gut their own market.

Gotcha. That one did do significantly better. It's interesting to compare that machine to today's. 5.6lbs vs today's 16" at 4.3lbs. 2012 is 0.93" thick and today's is 0.64". I suppose, based on this dat
