Ask HN: Where is the next tech frontier?
Fifty or so years ago, you only needed basic computing knowledge to be the head architect for the personal computer industry.  Today? 20+ years experience and vast political connections.<p>Where the computer industry was fifty years ago is what today?  What fields can you make a huge difference in without dealing with the "credentials" or "politics" that hamper other fields?<p>P.S.  I think the social web is also disappearing as the frontier since companies like Facebook are asking a lot for their new hires.
