I don't think at this point in history limitations drive the the way we do things, abundance does.

I don't see the underlying economic dynamics of the relevance of substitution costs driving the way we do things going away. And substitution costs are all about limitations.

Abundance and limitations are a bit of ying/yang phenomena in terms of driving things, you don't have one without the other.

Igor Stravinsky: "Constraint drives creativity"

(I also don't see Amdahl's Law --which is fundamentally about limitations -- going away any time soon.)

I do agree that there are compounding abundancies present.

Increasingly, the "what do we have the most of?" questions will return "RAM" less and less often.
