We broke the 2x graph for some time already. But that doesn't mean we are not getting 1.7x.

About 10nm. High-end chips have been there for ages now. Fighting those problems takes quite a bit of creativity.

That means that practically, the smallest conceivable metal pitch is 10nm, the smallest gate is 20.

From 5nm, it implies a factor of 10 is left, or about 3-4 nodes.i expect lower scaled nodes at larger delays, but another 15-20 years.
