The article also pointed out that even with future cost reduction from scale etc, some things just don't work well running off electricity, the energy density of hydrocarbons is very hard to beat unless you go nuclear... and for things like planes, baring any massive technological breakthroughs, it's probably gona have to be hydrocarbons for the foreseeable future... so synthesising those fuels by short circuiting the carbon cycle in a post "dig unreplenishable shit up from the ground" era, is pretty attractive.
