"It may surprise this fellow, but there are people out there that actually enjoy thinking all the time, and it's not about getting the best-paying job possible."
well, i don't think that was his point. well maybe a bit, since it was from forbes. but its probably true that the great era of discovery etc in computer science is over, and now its just lots of incremental change. though i'm not sure i'd agree that the next big developments will be in genetic tweaking. maybe. or the sequencing of the human genome might have been the high point there too ... and now biologists go back to what they do best which (i think its in the preface of the watson book) is stamp collecting. i.e. classifying, cataloging, etc.
geriatrics is the next big thing. actually, i remember hearing watson taking about how he felt that cancer would be solved within the next 20 years.
