Keeping in mind that we are talking about GAA FETs implemented using a 180 nm-class process technology, the practical applicability of this TPU is low, to say the least.

Research tends to happen on much older nodes. The two key questions are:

1. How do the CNT compare to similar CMOS transistors, on the same node?
2. How well do they think the CNT will scale down to modern production nodes, both in terms of performance and manufacturability?
