I always interpreted moores law as having 2 aspects, the scaling part (cramming more per mm2), and the economic aspect (for minimum component cost).
So when people say moores law is dead, it's often confusing as clearly things are still scaling (3nm crams significantly more transistors in than 7nm), but the cost per transistor has flattened, or possibly inverted a bit.
but the cost per transistor has flattened, or possibly inverted a bit.
No, that part is still accurate. There's still a cost premium associated with really large, dense dies -- and it's one of the major reasons why you see some manufacturers using chiplets to circumvent that.
