It was nearly a one-person project at beginning. Despite the fact that months ago, back in 2018, ideaupdater wrote that he planned to hire others for the project, but by now we can believe that he did not hire anyone else, and the project was abandoned. Hope from time to time, and honestly, till now I don't "see light at the end of tunnels" for Masternode coin. However, you are likely right that no one can take over this project, except when ideaupdater decide to give the project to community.
