It has not been long since Gordon Moore has passed. But for a few years before that, it was obvious that Moore's law, as it was understood inside Intel, is dying.
For Intel, Moore's was only about silicon and pushing for circuits with smaller and smaller scale metrology on silicon. This single minded focus made the company neglect investing in alternate technologies. They headlines with quantum processors etc. but underneath, such work never got serious funding and support.
As scaling on silicon is nearing it's end, we are now seeing Intel also following the path. All companies are finding it difficult to scale. But they kept the older nodes going, to sustain their revenues. Intel's mismanagement and failures over the last decade haven't left them with the luxury of having well matured older nodes.
Result is there for all to see.
