Carbyne: A Form of Carbon Even Stronger Than Graphene

Dialecticus writes: Sebastian Anthony at ExtremeTech has written an article about research into the physical properties of carbyne, an elusive form of carbon. A new mathematical analysis by Mingjie Liu and others at Rice University suggests that carbyne may achieve double the strength of graphene, stealing its crown and becoming the strongest material known to man.

Elevator-worthy?

So CNT's came up marginally too weak for a Clarke elevator per Pugno's 2006 analysis at http://www.ewp.rpi.edu/hartford/~ernesto/F2011/EP/MaterialsforStudents/Li/Pugno2006.pdf [rpi.edu]. Will carbyne be better by enough of a margin to work in the real world?
