He is probably right in that the economic system needs to evolve to keep up with technological change, but he misses the most important reason for that (the increased importance of products with negligible marginal cost of production), and he has no reasonable idea of possible solutions.

He is not content to be a cartoonist and has so far tried to write about physics (the last part of, I think, the Dilbert Principle) and religion (God Debris, which is a free download - he manages to come up with crude versions of ideas that Hinduism got to millennia ago).
