* There is so much more to life than a job. You will be a citizen; how do you decide on war and peace, economic issues, social policy, etc. without understanding history, politics, economics, social issues, other cultures, languages, etc.? Without being able to grasp and think critically about sophisticated propaganda, and how to challenge ideas? You will be a social animal: A member of the community, a friend, and maybe a parent. You will be a person, a being with an identity and life outside of your cubical; if all you know are technical skills for a job, what are you? What will you get out of life? Where will you learn about the things that make our lives rich, such as the arts -- you know, much of the content that is the purpose of the wires and systems you hope to build.
* There is so much more to a career than one job. If you focus your education on the skills needed for one job at one time, you'll find that soon both you and the world have moved on. The demand for skills change and, more importantly, you will change, and the skills will be obsolete.
* There is so much more to a job than technical skills. As simple examples, you need to understand other people, to undertand other cultures in the U.S. and around the world if you will sell to or help (or work with!) people outside of SV. As was discussed yesterday, some in SV still don't even undertand those people called "females" enough to realize they may not enjoy playing male characters. You need ideas, and most great ideas are outside tech and outside SV and older than 20 years; there are thousands of years of them.
What a sad, myopic, even egocentric view of the world and of education. I feel bad for the people who will encounter so little of the world of knowledge.
