Space Elevator & Graphene

The only reason why there isn't a space elevator yet is due to the lack of a strong enough material for the tether that can be manufactured at scale. However the International Space Elevator Consortium deems single crystal graphene to be a material suitable for a space elevator tether and recently there has been quite a bit of progress in regards to the manufacturing technique of said material. Large single crystal graphene is possible.

MIT has published an article in 2020 highlighting their new role to role production method that can produce any length continuous sheets of single layer graphene. They say it could be scaled up fairly easily. 

The south Korean company Charmgraphene seems to have done just that. Now all that's needed is a company with the focus on building a space elevator that puts it all together. Elon?
