While hydrogen might end up "being the future" this prediction has as much substance (perhaps less as there is no scaled up application of the technology) as Musk's claim. Just want to make the point that the idea of hydrogen still having a lot of potential and is worth investigating is a better claim than making a somewhat baseless assertion that hydrogen is the certain way forward over batteries.
