  After decades of uninterrupted progress and growth, information technology
has so evolved that it can be said we are entering the age of autonomous
machines, but there exist many roadblocks in the way of making this a reality.
In this article, we make a preliminary attempt at recognizing and categorizing
the technical and non-technical challenges of autonomous machines; for each of
the ten areas we have identified, we review current status, roadblocks, and
potential research directions. It is hoped that this will help the community
define clear, effective, and more formal development goalposts for the future.
