What has happened to Drucker's "knowledge worker?"

A while back, in the Q&A section at LinkedIn, I asked: Had Drucker gotten it wrong?

I have a great deal of respect for Drucker's multi-dimensional approach to problem-solving. I also think of the days when access to the largest dynamos of economical power in the US was as open as the one enjoyed by the late Drucker. Moreover, Drucker's (and Toffler's) heralding of the knowledge worker has made for many a hopeful among the sons and daughters of the industrial (cog-)man. However, in this day and age, more are coming to question what happened to the knowledge worker as described by Drucker.

Is there something missing in:

1. Drucker's view;
2. Today's workers' knowledge; or
3. In today's economic system as re-defined by globalization?

Please note that Drucker had maintained his belief in the knowledge worker up until he passed away in 2005. So, he got to see how internet and globalization were re-shaping the organization--in fact, he had us aware of the new type of customer, as enabled by internet, and even recommended a new type of organization (collaborative rather than competitive).
