> My dream of a general purpose OS is definitely an open source microkernel, multiserver RTOS with capabilities and an user experience that builds on those two systems. It is important for it to be an RTOS, as unbounded response times would make the system fail as a general purpose system and as a personal computer system.

This sounds more like a complete version of the Fuchsia Operating System, which has both technical and is more of a user-facing OS. That probably has more of a chance of meeting these requirements at the rate that it is being developed.
