Can a native speaker chime in on this? I didn't get it wrong, but my rudimentary understanding of Spanish grammar says "Doctors are specialists" and "The doctors are specialists" should translate the same, contrary to the many other responses. Something like "Doctors are important" translates to "Los doctores son importantes".
And preemptively: "Doctors are specialists" is a perfectly reasonable statement. Doctors don't casually drift between specialities the way, say, engineers do.
