I feel there were very good reasons that airships were abandoned. I don't know what those reasons were, but unless they enumerate the reasons and explain why they have now solved them, I will assume they are also going to fail.
According to AI, there have been 5 historical attempts to make airships work before the modern resurgence:
The early experimental phase (1780s–1850s), The pioneering era (1850s–1900s), The golden age (1900s–1930s), A post-Hindenburg decline (1930s), Cold War military uses (1940s–1970s), and A modern resurgence (1990s–present).
