CMMC is more about how well your processes work. Low level = more chaotic, stuff basically works but people have to scurry around and improvise when it breaks. Mid level = it can break but procedures for fixing it are documented and regular, and various good practices are followed to make it reliable. High level = can't break, very rigorous standards. No attempt at certifying to any level at all = never mind, just wing everything.
I wonder how much turning everything into piles of AI crap is involved with this.
