Moore's Law: It's Complicated

The Status of Moore's Law: It's Complicated - IEEE Spectrum:
"as chip foundries prepare to roll out 14-nm and 16-nm chips, custom-made for smartphone makers and other customers, that will be no denser than the previous 20-nm generation. 
...
simple transistor scaling reached a limit in the early 2000s:
Making a transistor smaller no longer meant it would be faster or less power hungry. So Intel, followed by others, introduced new technologies to help boost transistor performance. 
...
The semiconductor industry pulled in revenues of US $300 billion in 2012. "
