This doesn't bode well for Intel's 5nm and 3nm processes. Part of the problem with their 10nm process is that they tried to scale transistor density far more aggressively than their competitors. Jumping 2 nodes in one go is far more difficult today as feature size approaches atomic scale than it was 20 years ago. Better to have a process that's an improvement over the previous generation than to have a process without the yields needed to support commercialization (which is effectively no process at all).
