I am a longtimer but have always felt intel was lucky that IBM picked the x86 it easily could have been a z80 or 6800 and then where would this company be. With the monopoly that enabled lots of good and some very bad habits that permeat and are rotting the company in so many ways!
Now that Moores law is done, and new generations don't provide much but cost so much what is next? Intel can't scale to the next node and win just because it is ahead. They will actually be even to late for the next node. So much for process leadership, that has been squandered!
Now that ARM powers a billions new devices a year to a few hundred million for x86 it's relevancy is plummeting in standards and design. One used to say if it computes it computes best with intel. These days if it computes more likely than not it is ARM.
IoT and 5g are the great new battle ground but one with no standard that intel controls so they have no advantage of architecture nor have they any track record in modems or such open competition.
My prognosis more bad time very bad times!!
