I'm pretty sure we will continue to develop a different voice for appliances like we do when talking to kids or pets only this time it will be overly articulated orders with raised voice. This will indeed blend over into talking to subordinates.
But in real life we don't really have 'subordinates'. Even an exec has to be careful with how they treat their assistant least they make a complaint to HR for harassment. And rightly so, businesses are not the military. We don't have this unconditional Yessir obedience. In fact I'm surprised the military still gets people willingly putting up with that.
I don't think this will carry over to human interaction in the real world. We don't talk to each other like we talk to Siri either.
People mistake depictions of boot camp for day to day operations.
(Which is to say, the military is a highly regimented organisation, but the idea that it's all about blind obedience is very much not the case)
