Cost of memory transistors has gone up on the last couple of nodes. NVIDIA has complained about it publicly.
Batteries are not on Moore's Law and more of our systems are battery powered so portable electronics is not on Moore's Law. Transistors are not cheaper if you can't turn them on.
Power goes as area squared and voltage squared. We can't turn voltage down any further and cheaper transistors mean area goes up. This means that most computation chips are fairly close to their thermal limits. Transistors are not cheaper if your cooling solution costs 10x more.
