Absolutely no apologies needed for length of this reply, David, its very much appreciated, and also good for stirring up the pot here 
Youâve really influence my thinking about this move beyond fixed content, but I question/wonder about calling the dynamic experience of interacting as interacting with expertise- what do we mean from that? I can see that the means of interaction, and querying, is a step away from just absorbing content. I donât have another word for it, but struggle with consider it the power of lived, active experience, as I feel in conversations with people like you.
And I see people like you and say experience programmers who are leveraging AI in ways that I see as meaningful, but wonder too how much of that is build upon the experience, wisdom you have through applied âexpertiseâ. How will our learners now learning from this âexpertiseâ develop that same level of experience? Is it this kind of âexpertiseâ where information more often wrong is preferred because it is delivered more politely or more conversationally?
It seems like the hangups with âtraditionalâ OER and whatever this becomes revolved on ownership or credit, and licensing seen more as a means to protect intellectually property than to make it available.
I await your expertise
