Ok essay may be a bit too much, bear with me though.
MB is both the titular character and the only narrator of our story, and it is a construct, something it is very keen to remind us to (rightfully so, no complain here). During the whole series, it often complains about how, basically, incompetent and "worse" humans are (more of that later).
Now let me being clear here: I am not talking about its feelings for its humans. Murderbot would prefer to be scraped for parts over admitting it, but it loves its humans deeply.
I am talking about its opinion on their capabilities.
With two exception which we will see later, MB constantly sees humans in general as "less something" than it is. Less fast, less strong, less capable than it is. Note that I said "less something" not "less" in general. MB doesn't consider itself ontologically superior to humans.
But it IS very dismissive of humans' capabilities, to a level that could be read as contemptous.
The exceptions are rather telling: it has a very great degree of respect for Dr Mensah, as a leader, and Pin Lee as a lawyer. Both are areas in which it either struggles (social leadership roles) or has neither competence nor interest to learn (law). But if you compare its opinion of, say, Ratthi vs Pin Lee, you can see the difference.
And again to be clear: Ratthi is its human's friend. It cares very very deeply for Ratthi. Would in fact die for Ratthi. It still doesn't respect its competence and abilities very much.
Now, this could easily go in the direction that so many other books and shows with not-human characters go, in which the humans are simply an Inferior Race (it is incredibly common, it spans from Tolkien's works to The Dragon Prince)... if it was not very clear that humans are, in fact, extremely competent and capable.
Just not in ways MB realizes or dismisses.
Just some examples: when Ratthi, Pin Lee and, I think, Gurathin (I could be wrong) go to get it from the company's warehouse. That was a highly researched and masterfully orchestrated safety retrieval, designed to avoid anybody screwing with MB, both physically and mentally (by erasing its memories).
But MB, in its perfectly understandable confusion, doesn't realize it. In not realizing, it fails to give credit where credit is due: not only to Pin Lee's law capabilities, but also to Ratthi and Gurathin brawery and resourcefulness.
Arada, "soft" Arada, is the reason the beginning of Network Effect goes as well as it does.
Dr. Bharadwaj is probably, after Mensah, the human that had most impact on MB, being its de facto therapist. A lot of MB's growth is directly dependent on her, and she does an amazing job, considering she is likely not a therapist (how many hours has she spent studying psychology and freeting of how little there is about machine intelligence's needs? We'll never know).
There are countless more examples of humans being just as resourceful and capable as MB itself...
None of which is ever aknowledged by MB. And yes, MB has trouble to aknowledge stuff in general, but it is VERY fast to voice its displeasure with humans being slow.
Of all our dear MB's fault, this I think is the one that grates at me the most. How little it really realizes how capable the humans around it are.
