Everyone should read this post, the origins of copyright are very enlightening when trying to understand the insane system we have now.
Intellectual property is system of monopolies inherently incompatible with a competitive, creative and innovative free market, how the IP-industry managed to turn this argument around in the minds of most people is truly scary.
Go is mind-stretching in its practicality and pragmatism.
Most (but not all) its ideas have been implemented before elsewhere (but then, that is almost bound to be true of any new language).
But the real 'innovation' is in the careful selection of those ideas and in how well they work together _in practice_.
This puts off people who are used to this or that feature in other languages, Go is not about checklists of features or abstract arguments about how languages should be, it is about what works really well when you sit down to write (or read) code.
There have been many changes to both the Go language and the stdlib, but it is really easy to keep your code updated (specially since gofix was introduced: http://blog.golang.org/2011/04/introducing-gofix.html ) so this should not be an obstacle to learning the language.
That said, version "1" of the language is due for early next year, which should provide a long-term stable language and set of libraries, for details see:
Also, most modern software/hardware is not particularly exciting from a usefulness point of view. It is mostly the same stuff that has been around for ages in a slightly smaller package with a new coat of paint.
It really depends on the person and how they use that technology. People like I assume Gibson use tech as a means to an end, he hasn't bought a new app because he is comfortable with what he has and sees no need to try new things.
This is the same reason my mother had a hard time when she bought a new laptop with windows 7 on it, though surprisingly she really likes google chrome and tells everyone on a computer using internet explorer they should use chrome instead.
I guess the gist of what I am saying is that sometimes change can be to much for those who aren't the power user. I loved windows 7 on the RC and all the little improvements, the same with word and office 2007. I get excited about new OS releases and new programs and updates because I find them useful and it doesn't take me hours or weeks or months to become more productive because I live tech but others just don't have the time or desire to understand it.
