I realize this is going to fan the flames a bit, but even procedural fields that people think are safer probably are not. Sure no one is yet talking about letting a non-MD do neurosurgery, but things like colonoscopies and cardiac caths....
Comparisons of Screening Colonoscopy Performed by a Nurse Practitioner and Gastroenterologists: A Single-Center Randomized Controlled Trial - PubMed (UC-Davis study, conclusion: "Cecal intubation rates, duration of procedure, sedative, and analgesic use, and patient reported procedural pain scores were equivalent among the groups. The GI-NP group had a higher adenoma detection rate compared with the combined GI-MD groups (42% and 17%, respectively, p = .0001) and a higher satisfaction score when compared with the combined GI-MD groups (mean 5.9 ± 13.81 and 8.6 ± 16.11, respectively, p = .042; visual analog scale 0-100 mm, "0" = completely satisfied, "100" = completely dissatisfied). There were no immediate complications reported in any group. The properly trained GI-NP in our study performed screening colonoscopy as safely, accurately, and satisfactorily as the GI-MDs.")
Here's a blog post from a Professor of Internal Medicine at OSU and medical director of one of their hospital discussing how he would "theoretically" implement a training program to create NP/PA endoscopists that would be much cheaper than a GI doc:
As I prepared to write this post and discussed it with my colleagues, there were only two responses: this is a great idea and this is a horrible idea. When it comes to abdicating physician clinical…

Here's the meta-analysis he cites as evidence for the safety of it out of UCSF:
Non-Physicians Performing Lower and Upper Endoscopy: A Systematic Review and Meta-Analysis
I suspect the real answer for most fields is: (1) Splenda88's suggestions above of putting yourself in position to FIRE ASAP and (2) get involved with the admin side to advocate against the things noted above. It seems highly likely medicine in the US is going to change dramatically over the next 10-15 years.
