Re: I don't get it...
"I seem to remember that 10nm was considered to be a bad idea"
Process node sizes are largely arbitrary - they signify a position in a hierarchy for one manufacturers processes but because they are made of of so many different measurements calling it 10nm instead of anything between 8 and 13 would likely indicate the same thing.
Known measurements for the respective processes is available here - Intels 10nm is "smaller" than TSMC and Samsungs 7nm. At present, Samsung looks very promising for next gen (Intel 7nm/5nm TSMC/Samsung):
