I think AI and robotics are very different things. We are replacing lots of people with robotics software. A computer doesn't need to be logical, it just needs rules. Doesn't matter how complicated tax rules are, you can always cover every eventuality. Data entry, even when human input is required can be replaced by robotics.
When you 'chat' with someone online, when you seek help on a website, you quite often aren't talking with a person. Not initially anyway. The replies in an early conversation are very predictable.
But as you say, AI takes that a step further, where behaviour is modified depending on outcomes. I would guess robotics is much more advanced than AI.
