Here are four short features from my micro-blog (Tumbld Thoughts) that creatively discuss the current and future state of Artificial Intelligence/Machine Learning research. Featured are: LIVE from Annoying Valley, Internet (I), Thinking more like a theorist...... (II), Trends in Future Research (III), and The path to machine consciousness will run through the executive network (IV).
I. LIVE from Annoying Valley, Internet
Here are a few readings  on how recommender systems and other intelligent agents go AWOL on a platform of creative destruction. Ads such as "enlarge the size of your portfolio using this one simple trick"  are an example of the "annoying valley", which is a version of the uncanny valley ubiquitous in human-robot interaction.
Thanks go to Calvin and Hobbes (Bill Watterson), and Thomas Hobbes and Joseph Schumpeter for the quotes (reworked from their original syntax).
II. Thinking more like a theorist......
Now, I think I'll get in touch with my inner theorist. Sheldon from "Big Bang Theory" summarizes the story of my academic career (at the 00:10 mark). What can we do Glenn Shafer's mathematical theory of evidence ? How about enabling complex data fusion and context-aware robotics (see figure below)? Next, Paul Krugman brings us his thoughts on the purported death of economic theory. Last but not least, a group of psychologists ask under which conditions theory can obstruct research progress . This can be contrasted with the exclusive use of naive theories (e.g. common sense models) in AI research.
III. Trends in Future Research
Here is a Quora thread on the top problems in machine learning. Answers range from a bulleted list of hot topics to longer discussions. Major problems (as defined by the crowd) include: gesture recognition, learning from social networks and media, deep learning , newsfeed aggregation, and scalability. Interestingly, there is only moderate overlap between individual answers.
Also interesting is the related Quora thread on important problems in the field of Artificial Intelligence over the short term (5-10 years). It will be interesting to see how these predictions correspond with future breakthroughs and developments in the field .
IV. The path to machine consciousness will run through the executive network
"Attention (awareness) is a data-handling method used by neurons. It isn’t a substance and it doesn’t flow"
Interesting quote from a even more interesting story  by Michael Graziano, a Neuroscientist at Princeton. He makes the case for how and how not to study consciousness. While theories of consciousness are plentiful, he argues (along with Christof Koch  of Caltech/Allen Brain Institute) that consciousness is primarily of phenomenon of attention and mental reflection.
Returning to the quote. If consciousness is a form of awareness, and awareness is a model of attention, then they all seem to be a data handling procedure the brain uses to select and reflect on information from the environment. In that sense, it is a non-physical entity that does not operate like a physical intention . The flow of physical intention can be distinguished from experiential flow involved with creativity  or the flow of information in attentional networks of the brain . By contrast, the idea that consciousness flows into objects in the environment (e.g. a portrait or object) is pre-scientific superstition.
In addition, there is also evidence (highlighted in Graziano's article) that consciousness is largely an "after the facts" mental construction, which feeds back to subsequent attentional selection. What is the missing piece of science's understanding of consciousness? Graziano's answer might surprise you.

 Graziano contrasts consciousness (the awareness of stuff) with "extramission theory", a naive theory that posits human control over the natural world using visual cues.
