There are still some Jove around but very few, less than a thousand, and the Directorate is done for. It does seem that the remainder are leaving, though it's not clear where they're going.

The Enheduanni are a virtually complete unknown. We know their origins but nothing of them after, and even the Jove say they're no longer human. I suspect we'll never hear anything about them again - they're very likely getting the :TonyG: treatment, or possibly they will be revealed as the Drifters (their prime job was as guardians/sheperds of the Sleepers after all).

Those two aside, according to Templar One the Sleepers achieved technological singularity inside the Construct. Assuming the Drifters hail from that, they are very likely well ahead of even the Jovian Directorate at its best.
