Since DOTS has been released in a stable build, it would be amazing to get a walk along from the GameDev.tv teaching style.
Perhaps by showing when to use ECS (in a populated scene, cubes all bouncing at random heights), then comparing this to the performance of the Monobehaviour and possibly showing how viewing the data is more efficient with debug logs.
Then a Final example of a hybrid style, using DOTS for Navigation, and Monobehaviour for something else, highlighting when ECS can be used and when Monobehaviour can be used.
