In the field this is the idea of General Intilligence versus narrow intelligence.

Alexa, for example, is an Artificial Narrow Intelligence. It can process speech and then follow different scripts with instructions derived from that speech, but it often fails comically so you as the human have to talk to it just right for it to work. Not too different from a verbal command line.

Meanwhile a human personal assistant has general intelligence. You can just tell them what you want and they can understand and figure it out.
