For those of us who take a critical attitude towards technological development. If you believe:
that technology has caused very severe problems, and will not necessarily continue to solve these problems;
or that technology is not "ideologically neutral", but intricately tied up with the structure of class society;
or that life in primitive societies is often fairly reasonable, and is not, as Hobbes said and as has become a popular view, "solitary, poor, nasty, brutish, and short";
or if you in any other way reject blind faith in technological progress - this is the group for you.
We believe that if humanity is to achieve a classless society, or even just make significant improvements in the short-term, then a significant critique of technology is necessary.
