One thing that is maybe helpful to consider in the modern era is that Moore's law's meaning has unraveled as we have reached smaller scales (hence the basic arguments over what it even means).
Originally the law relates to the transistor density of an IC, but this was strongly correlated with Power Consumption, Clock Speed, and a bunch of other metrics. As we reach smaller scales these parameters are no longer tightly coupled. I recall seeing a plot to the effect that Power Efficiency tapped out at 14 nm. Likewise clock speed has not been increasing at the original clip for the better part of a decade (it went up ~50% in 10 years, which in any other area of engineering would be astounding, but I could sure use a 32GHZ processor).
Anyway, having trade offs makes things more interesting and perhaps we are going to see an era with more cleverness chip architecture soon.
