In my simpleton mind, I cannot understand why we do not use more blimps for transporting goods. Seems engines and fuel could be done with solar, also seems like they could be automated. Is it simply not cost effective? Is it dangerous even though modern blimps use helium? Eli5.

Veritasium made a video about this question recently. Well worth watching.
One of the main limitations, is for them to be big enough to replace trains/ships and haul cargo, they’d need to be massive. It’s also very difficult for an airship to hover in place to allow loading/unloading of cargo.
