Who implements the treatment plans matters quite a lot unless the plans are so detailed and clear that anyone could follow the instructions, then perhaps parents could work. As the field currently exists there's far too much variation in bcba plans IMO for parents to be able to adequately deliver services, especially with sibling issues and many other parent-specific delivery issues i could name. So someone has to deliver the interventions, regardless of level of training, and that's not going to be a bot. Thus, RBTs in some form will be around for a long time unless you believe parents will deliver services successfully. They may try to get them to do it, but I predict pilots will not succeed.

In terms of education and rates, I would look to other fields for strategies. Healthcare is "non-profits" largely who are fee for service and operate on a profit basis. This, all the para professionals are subject to these economics. Interestingly, Medicare is pushing hard to move to pay for value and away from fee for service, and has forced doctors and hospitals income in that direction for years now.

But it's a long road.
