(3) is what I'm talking about though. There is not enough demand for smaller and lower power processors because at the edge where size and power matter the most there are not enough applications that can profitably use more power. Data centers are easier to scale by just adding more nodes. Power matters a lot in data centers but otherwise miniaturization is less critical and single threaded performance is less critical.
