Future of air travel, as of 1975

I don't know where the people at BoingBoing find the things they do, but their latest discovery is a 1975 video from the Institute for the Future depicting the future of supersonic air travel, complete with video phones, jetpacks, myriad personal robots and plenty of egg-shaped chairs. Link to the video on YouTube.

According to the video, "There's no waiting in this supersonic age, and very little walking." I wonder if robots do your workouts for you too?
