Potential Drawbacks  Could someone please remove this column from the list  The potential drawbacks of emerging technology should be addressed in the articles on those technologies themselves  The list feels cluttered with long and unnecessary speculations on possible negative consequences of these technologies  The space available on this list is simply not sufficient to address the potential drawbacks in detail worth devoting a column to      Before the addition of additional columns it would be good to debate the merit of such columns and their purpose with respect to the objectives of this list
