technology as a social construct?

I really enjoyed Coleman's interpretation of race as technology. I think it helps us get out of the anxiety and frustration regarding the status of race, especially in an openly multicultural society like the the one the structures of power in the US say we have. And I bring up the following point in hopes we can work through it because I do think race as technology is a revolutionary way to frame race in many respects, but how is this formulation of race as technology different from the "social construction" arguments? In what ways are tools/technology not a literal "construction" of society and its people.

Furthermore, I think we should talk about the postscript. It was a lot to think about and the idea of process is very intriguing, especially since Coleman in large ignores temporality and the Grand Narrative brought up by Snead.
