This is a most excellent place for technology news and articles.
There is a lot of biofuel being made of other fuel types though, so no reason why production of aviation biofuel can't ramp up.

Most of what our liquid fuels are used for currently can be done by electric vehicles, it will be tasks like farm equipment, and vehicles and equipment working in remote areas, that will still require liquid fuels.
