C'mon guys, this is simple. Because we have not yet designed and implemented true, constantly forwardly/backwardly evolving, energy-transforming living machines which will enable us to perform all functions from the informedly turbining hub of a single autonomous in-spiralling/out-radiating network of space-connected information vector transforms. Had the chicken been supplied with my Dymaxion Tensegrity Coop, it would have remained at home, un-tempted by such risky spatial-temporal translations. DUH.
No guys, no. I think the real question here is whether or not the chicken is crossing the road, or the road is crossing under the chicken.
