Clarke was both right and wrong about telecommunication, though. Yes, I can and do my work pretty much regardless of where I am in the world. I make videocalls even more conveniently and cheaper than envisioned in "2001". However, only during the past year, I have travelled several times related to work: Beijing, Prague, twice to SF, Chicago and Seoul, and now to Singapore. The year before that: Buenos Aires, Berlin, Tokyo and multiple times to SF. The irony: it's all for standardisation work enabling videoconferencing.
