It's a problem. Because in the 1930s (and still today), making mathematical calculations on partial differential equations with several dimensions, including 3D of space (like the Navier-Stokes and Maxwell equations) is well, very hard. Like, very very hard. So the field was essentially stuck. Also, you don't find a fluid conducting of electricity everywhere, in a laboratory there are very few that do the job: liquid gallium and sodium essentially, and they have very bad properties otherwise. So, doing experiments was very hard too.
