I think this is a great point, but I have to disagree with two parts.

Here comes the internet with zero cost of communication - information still costs time (opportunity cost) to produce and consume. It can be designed to be easier to produce/consume, but that costs design resources. The Internet gives zero cost to transmit information.

Here come high level languages that make it cheap to describe the most efficient processes. - this won't happen because people are not interchangeable like Silicon is. You can hire two people that fit the same job description but will fit differently into the organization. They will work differently, interact differently with management and coworkers, produce different results (even if equivalent).

I think the closest we can come to high level business languages are

1) something like design patterns that can't be plugged in directly but can guide implementation of a business process with known trade-offs OR

2) design processes that can be completely specified and automated so human judgement isn't involved

Interestingly, #1 favors talent cultivation (a la Google) and the second leads to outsourcing.
