I hold both John Sowa and Kingsley Idehen in very high regard, but this
thread really touches a nerve. It's like arguing the merits of different
brands of trucks as an 18-wheeler careens toward children walking across
a street. (01)
The number of people (and businesses) who can benefit directly and
substantively from such massive database processing is tiny. It's a
"solution" for those who benefit economically from processing massive
amounts of data. It's trickle-down techno-economics. (02)
Better logic and higher processing speed may generate income for a few
billion-dollar businesses in the same way that large oil companies apply
new technologies to squeezing the last drops of oil out of depleted oil
fields, but they do not generate new value. People do. (03)
Semantic strategies and a broad spectrum of technologies that enable us
to contribute more effectively to the organizations in which we
participate (as well as to our personal bottom lines) and enable us to
interact more effectively with our information-shrouded realities are
more important than the processing of massive amounts of data. (04)
Getting the right data and/or creating it incrementally in a
**meaningful form** and connecting it **directly** with the creation of
value is the more important problem. That's what will generate
persistent contributions to the efficiency, competitiveness, and
sustainable growth of knowledge-based businesses. (05)
