That can sound great, at least from a scientist's point of view, the issue is that many times those "things the scientists don't know about" are taken as a given (i.e. closer to the "truth" compared to the things that non-scientists reason about) and they come back to bite us non-scientists, meaning the general public.
This virus has proven just that, with scientists in many countries believing lots of different things (they still do, even after ~4 months since the whole thing has reached a new level), about which things it was obvious "they didn't know that much about", but it didn't matter, because most of the time their voices were heard louder compared to everyone else's and as such the powers that be decided to follow those scientists' lead/advices.
In other words, it's ok that scientists don't know everything, but they should also be aware of that and they should let their "superiors" (government officials, people having the power to influence the lives of millions of other people) know about them not knowing everything. Going back to this virus, I've personally never heard an "expert" say out loud in the media something like: "we just don't know how this virus really works and we really don't know how best to fight it, we're really navigating in the dark here, we're asking you to stay locked-down in your houses because we think it's the right thing to do but we can't say exactly for how long because we really don't know".
