Guys (and gals) go look for a virtually forgotten collection of articles & essays by Isaac Asimov by the titles
"Is anyone there?" and "Where do we go from here?".

The articles were written in the 50s and 60s and assembled at the end of the decade.
50 years later, the assumptions made and the technology assumed are... moving...

If only Asimov (back way then) could have had just a glimpse of today's average distributed technology (i.e., iPads and iPhones) he would have been shocked.
On the other hand, he would have been disappointed by... no Permanent Space station with a hotel in it, no Lunar Station...

... nobody on Mars yet (what? Man on the Moon in 1969 and then you sit on your hands?)...

And most of all, apparently no Close Encounters of any kind (save for the journalistic bit

)
I'm an Asimov fan, does it show ?
