I'm not really well versed on drilling rigs but it seems that automatic sensors could be made to help monitor this type of thing that would trigger an alarm or automatic shutdown

Alarms are constantly going off on a rig floor and sensors do exist but making sure the well is displaced correctly still requires human interaction. If the rig starts filling the well automatically it would create mass confusion. Sensors can give false readings and a multitude of things can be taking place that requires interpretation to react accordingly.

A rig floor is already a chaotic place and trying to interpret what the well is doing can become confusing without the rig doing things automatically.
