Few more generations with the new Moore's law, means a decade?

  Give that full generational gains are definitely slowing, yes, but there is no "iron wall" yet for squeezing a 4 fold gain. Existing fin/gaa fets can get at least 2 times smaller themselves in both dimensions. 20nm gate length does not look impossible. Device spacing can get smaller with existing tech, and trench to wall move will add to that. Metal is actually the biggest worry from what I heard. Lab scale demos for metal capable of 1BT/mm² were done long ago, but contact, and line defect rates are still unworkable, and arise from very fundamental metal deposition physics issues. A completely new approach to building middle end, and M0 may be needed.
