I think you two are talking about different things.

You're talking about Autopilot which is just driver assistance technologies; lane keep assistance, adaptive cruise control, blind spot monitoring, etc. It's not to replace driver attention, it's just monitor sections of the road the the driver can't pay attention to full time. The driver is still remaining in control and attentive to the road.

The person you're responding to seems to be talking talking about the Full Self Driving feature who's initial marketing implied that the driver need not be mentally engaged at all or too impaired to drive normally. Which was later back pedal led to say that you need to pay attention.
