I wish this wasn't so laughable. What this really shows is that IBM has high margins for their chips, and a long standing tolerance for absurdly low yields and long wafer turn times. That they announce "production" before any of the other fabs is more likely do to PR needs than real technical advancement.

We aren't there yet (but probably will be in a year or so- they've gone from 100W to 150W in the last 9months and need to hit 200-250W).<p>Will we have 1-3nm transistors? Yes.
Will they be commercially viable? Probably No.<p>Moore's law ends when the CFOs decide it's not worth building another multi-$B factory on schedule based on net expected return... which already happened over the last 4 years. Sorry, downvote at will.
