With Intel squarely stating it wants to go back to a two year cadence, that implies that Moore’s Law will live on for a few nodes longer.
I'm not sure it counts as being on a "two year cadence" when the only reason their 7nm process is supposedly coming relatively soon after 10nm is because 10nm was delayed for so many years. Intel was similarly talking about how they were going to maintain a process advantage with 10nm around the time they launched 14nm back in 2014. Then, 10nm was delayed until late 2017, then 2019, and we still have no 10nm desktop processors even on the roadmap for 2020. It will have taken at least around 6 years for Intel's desktop chips to see a process node shrink from 14nm by the time they come out.
Also, these nodes are not as well-defined as they used to be, with only certain parts of the processor dropping in size. Their original 10nm design was apparently not tenable, so they scaled it back to get what they are now calling 10nm, and a few years later than expected, at that. Their 7nm process might end up being more comparable to what they had originally planned for 10nm to do a few years ago.
I would not consider that as "Moore's Law living on". Process advancement has clearly slowed, and we are not seeing the number of transisters in a given area doubling every two years, by any means.
