I've always preferred to use classical "fine" artists as an metaphor for development language preferences. Artists don't just pick up any medium at a whim, most have specific mediums that they excel in and ignore the others. For example Van Gogh produced his most famous works in oil paints. He had worked in other mediums but his talent definitely seemed to shine when working in oils and when he first found oils he took to them quickly and adopted them as his primary medium.

Most people definitely seem to have specific preferences built into their talents. I don't see why programming or programming languages would be any different from any other medium or art form.
