hang on ....not every one work in a office you know some of us have other work than computers ..:O)

Some jobs require physical work, because a machine doing it adequately has not yet been invented, or would be more expensive. (Well, your native fishing industry owns trawlers that produce deepfrozen fish fingers on the ocean completely automatically. Modern air pilots have no other function than to vouch with their lives for the safety of the airplane.)

For some other professions, such as concert musician, priest, or prostitute, physical presence is the main point. All other work, particularly administration, but also supervising, teaching, jurisprudence, selling/buying, etc., can principally be done remotely via internet. This applies even to medical advice to a surprising extent, as demonstrated by isolated farmers in outback Australia. Often a physical action, such as an injection, can be performed by a person less qualified than the one ordering and supervising it from elsewhere. So I am by no means talking about classical computer jobs only.

Of course, human interaction is necessary for almost all work to be successful. Our telephones being immensely helpful, video conferences and video supervision have much greater potentials. To be sure, they will never be quite the same as physical presence, both having their specific advantages and trade-offs.

On the whole, a large part of today's traffic is wasteful even by present technological and economic circumstances, let alone environmental aspects. Most of our managers, shareholders, politicians, and voters are not sufficiently aware of these facts, and/or worship cars and airplanes as status symbols. May this change as quickly as possible.

If there were less demand for energy, prices would not rise that much for what is still needed.
