There are maybe some advantages to a hybrid system.

The higher reliability of electric.

Losing an turbine engine doesn't mean asymmetrical thrust. Plane still flies normally.

Losing an engine on takeoff you still have full power.

Electric motors spin up faster than turbines. Which means faster throttle response. Which you need when hit with a wind shear on landing.

Take off and landing under electric power means much less noise.

Efficiency, you can increase the number of props or fans to get a much higher bypass ratio. Worth noting the plane in the video has four props.

I’ve been tinkering with the idea of a hybrid system where the ICE system is its own bolt on component to an electric aircraft that is used for takeoff and altitude before it detaches and returns to the airfield before the aircraft cruiser on electric power. Could even have a rocket launch version for cargo
