Hum, I think things should be broadened beyond just a fast/slow axis, and inquire what some of these projects actually serve. Or at the least what they've costed in the long-run in terms of resource use.

Personally I've been meaning to really do an exercise in evaluating projects against a regenerative framework (see https://capitalinstitute.org/8-principles-regenerative-econo... & http://fieldguide.capitalinstitute.org/whats-regenerative.ht... ). I'm not saying this framework is perfect nor am I endorsing Capital Inst, but there needs to be better evaluation than just speed.
