I'm not sure wind and weather are solved. Planes, ships, and to a lesser extent cars/trains are still lost to weather quite frequently. Yes, we can track it better, but people still have to go about their lives in inclement weather. Knowing where it is does not mean we never have to deal with it.
Also, as others have noted elsewhere, hydrogen is still an absolute pain to work with. It's better than it was, but that doesn't make it safe. In-flight fires are still a nightmare on planes - it'd be much worse if the only thing keeping you in the air is a massive hydrogen balloon.
All this is apart from airships being slow, unwieldy, relatively low altitude, etc.
