BLS statistics say there are about 1.1 million "Security Guards" employed in the US. [1] (For comparison, the total of Taxi Drivers and Chauffeurs, Heavy and Tractor-trailer Truck Drivers, Bus Drivers, and Delivery Truck Drivers and Driver/Sales Workers is about 4 million in total [2].)

Is it reasonable to compare the scale of impact that this might have in the security space, compared to, for example, how self-driving cars might impact space of professional drivers?

Knowing next to nothing about the physical security world... what fraction of these roles are serviceable by a robot like Cobalt's video shows today? What further advances are required to be more useful?
