Following on from my post yesterday, this from Horace Dediu (@asymco) and his blog at http://www.asymco.com, also posted yesterday, is good reading:
The technology is one part of the problem to be solved, the other is how to get people to use it. And that problem is rooted in understanding the jobs people have to get done and how the technology can be used defensibly. That’s where the rub is. An unused technology is a tragic failure. Not just because it has no value but because the resources (those beautiful minds) used in making it could have been applied elsewhere.
The whole thing is here.
