Doesn't leakage increase again below 22nm because of tunneling losses, though?
Of course, the lower gate capacitance allows for lower switching losses. But adiabatic computing could theoretically recover switching losses, allowing for higher efficiency at older nodes. That can be approached by using an oscillating power supply for instance, to recover charges. If someone was to design something like this for this run, it could be very interesting.
Now I'm wondering if this isn't some covert recruitment operation by Google: they will likely comb trough application, select the most promising ones, and the designers will get job offers :)

Dielectrics got better as nodes shrank, and this is the reason FinFETs became practical (which switch faster, and more reliably on smaller nodes, but leak worse.)
