They lament that the mouse pointer has "barely evolved" in half a century, ignoring that people have tried to "evolve" the mouse cursor only to find that the only option people really wanted was to have a left-side cursor for southpaws, and maybe to change the color for visibility.

In terms of computing power, having to run AI queries as the pixel moves is an enormous waste of power. We have left clicks for activations, right-clicks for context menus, and that's enough for 99.99% of tasks, and it only causes the computer to take action when we are deliberate about it by clicking.
