Well, I was very interested in the article.  Maybe these projects will not
work out; it is good to know people are working on things.  Many of the
things discussed are already available in one form or another.  I like to
know about potential breakthroughs.  I remember way back when there was a tv
program which talked about possible things of the future, one of which was
robot-type cars needing no driver, just a punch card.  It has not happened
in the real world, although something similar was tested in the southern
California area, I believe; did not hear outcome of that test.

The worse thing, to me about hearing about projects like these is that so
often I do not get to hear follow-ups.
