Having not watched the video, obviously hydrogen is a bad idea, but I'd also say no to helium airships until it becomes a replenishable resource through nuclear fusion.

Do you have any idea how much fusion you'd have to do to have it be a significant source of helium?

*edit: I was curious but had to guess ranges to do the maths. To fill a single Flying Whale airship, a 2 GW fusion plant needs to run between 90 and 850 years.
