Stanley, you sound like an anesthesiologist years ago saying nurse anesthetists are not safe. The anesthetists got in, they were proven safe and they are now accepted. The AAs are coming. I have yet to hear of a state where they came in that they got kicked out. I understand how you being new to the profession are fearful of your future.
Do a good job, be safe and you will not have to worry, you will always have a good paying job.
