The “exponential growth” of computer technology is most immanently apparent to me in the area of communications rather than the focus of Zurzweil in “The Singularity is Near”.  We simply do not yet have the “subject” (in Kurzweil it is the brain/mind)  figure out; sufficiently “mapped out”,  or even yet have much of any confidence in how the brain does what it does.  Even if we figure out a really good model of what is going on where and when as a particular thing happens or a “thought” occurs,  how does that help really help us write a “software” that takes those “events” and “receptors” and “receivers” and “storage” and create something like a “though process” or figure out a “problem”?

It seems to me that we are much further down the road in useful processing of communications.  Increases in audio and video fidelity increase the “realism” of the experience of a conversation or meeting of another group or individual.  What might happen as our fidelity approaches that of “full immersion”?  When we are no longer viewing the other end on a flat screen,  but as “sensed experience” that is taking place around us?  And that’s just the audio-video-sensory experience?  What about the vast possibilities in making a limitless array of “other” resources available to us DURING  (and also prior to and AFTER) the communication experience?
