I really wanted to see Buildings that were 4x lighter, aeroplanes 5x lighter, solar cells > 50% efficient, Chips sped up by 5x beyond 7 nm, Solar desalination getting 10x cheaper but i have settled for the fact that Graphene is never going to be cheap enough to be mass produced unless by luck someone invents a process that works. It will be restricted to niche applications based on its cost of production at a given point of time assuming it does provide enough benefits at that price point.
