Of course there is something like expertise. But the really accomplished experts are winging it most of us all, because they are at the frontiers of human knowledge, trying things that no one has tried before, stepping where no one has stepped before. So what else can they do than wing it. And regarding the possibility that someone becomes an accomplished expert in a field and then never tries anything new? It must be exceedingly rare. If you don't have the temperament to always try new things, you rarely become a true expert. And a true expert that can't try new things rapidly becomes bored to death.
