I was at a talk the other day on sustainability. During that talk the speaker used the term (B)leading edge of technology. It’s clever. I had not come across it before. Stay tuned for a post next week to illustrate why I think that term is coming into popular use. The context in which it was used was pre-emptive … it seems now that many in the sustainability community are fully aware that their projects pass no economic cost-benefit test and not often any environmental cost-benefit test either. So now we move onto symbolism. We have to “bleed” and incur the pain of show projects – otherwise nothing will ever get accomplished.
