Biofuel for land vehicles is largely dead, or rather limited to legacy systems (Brazil etc). Whatever EVs can't do (if anything) will likely be taken up by hydrogen.

Biofuel for airplanes however will probably be around for a while. Unlike cars, airplanes are usually built to last for decades. It might be possible to fly planes fuelled by hydrogen or ammonia, but many of the planes currently flying today should still be flying in 2050 -- not necessarily a bad thing because building an airplane isn't exactly low-impact. Synthesizing jet fuel from plant matter is probably easier than starting from "scratch" (syngas).
