Progress might be logarithmic in compute, but compute (transistors/sqinch and transistors/$) is growing exponentially with time.
Despite what skeptics have been saying for decades, Moore's Law is alive and well - and we haven't even figured out how to stack wafers in 3 dimensions yet!
Oh wow! Could you please share what processors are exponentially faster than those of 10 years ago? I'm not seeing any here: https://www.cpubenchmark.net
Macbook Airs have 20 billion+ transistors, compared to 50 million on the Pentium 4 in the early 2000s. Moore's law is about transistor density, not processor speed, which is gated by thermal limits.
