I heard a hypothesis that the first human made consciousness will be an AI algorithm designed to monitor and coordinate other AI algorithms which makes a lot of sense to me.

Our consciousness is just the monitoring system of all our bodies subsystems. It is most certainly an emergent phenomenon of the interaction and management of different functions competing or coordinating for resources within the body.

To me it seems very likely that the first human made consciousness will not be designed to be conscious. It also seems likely that we won't be aware of the first consciousnesses because we won't be looking for it. Consciousness won't be the goal of the development that makes it possible.
