Please elaborate on what you think the issues will be? Why read documentation when you can simply ask questions and get better contextualised answers faster? Whatever edge issues manifest they will be eclipsed by greater productivity.
Its one thing to have the AI work through the materials and explain it.
Its another thing to have lost a lot of the background information required to sustain that explanation.
Greater productivity, is of course, a subjective measure. If that's all that matters, then being glib is perfectly acceptable. But, the value of that productivity may change in a different context - for example, I find it very difficult to go back to AI-generated code some months later, and understand it - unless I already took the time earlier to discern the details.
