The return of airships would be amazing and insanely safe. To bad public opinion of airships still reflects late 1930's. With today's technology why wouldn't it be safe?
I've love to ride a blimp, but it's hard to forget the imagery of the Hindenburg. Just like Adolf isn't exactly a popular name for kids.
I'm reminded of the Archer episode "Skytanic" and the main character's failure to grasp that the blimp they're on isn't going to explode from every little spark:
---SNIP---
Sterling Archer: Jesus! You want to blow us all to shit, Sherlock?
[Archer slaps the face of a man attempting to light a cigarette]
Malory Archer: Sterling!
Capt. Lammers: For the last time, the Excelsior is filled with non-flamable helium!
---END SNIP---
While Archer is a silly comedy, in the end, that's the mentality we'd have to face to get something like this mainstream again.
Another place where airships might be useful for transportation is Africa. Lots of resources that need to be moved around, (mostly) terrible road and rail infrastructure. And there the airships wouldn't have to be very high-tech to be safer than road transport.
Why do you think they will not be the future? I'm not saying they will, but I'm getting very tired of people shooting ideas down without giving a reason why.
