I'm not making the case that LLMs learn like people. I'm making the case that if your system is hardened against things people can do (which it should be, beyond a certain scale) it is also similarly hardened against LLMs.
The big difference is that LLMs are probably a LOT more capable than either of those at overcoming barriers. Probably a good reason to harden systems even more.
There's benefit to letting a human make and learn from (minor) mistakes. There is no such benefit accrued from the LLM because it is structurally unable to.
There's the potential of malice, not just mistakes, from the human. If you carefully control the LLMs context there is no such potential for the LLM because it restarts from the same non-malicious state every context window.
There's the potential of information leakage through the human, because they retain their memories when they go home at night, and when they quit and go to another job. You can carefully control the outputs of the LLM so there is simply no mechanism for information to leak.
If a human is convinced to betray the company, you can punish the human, for whatever that's worth (I think quite a lot in some peoples opinion, not sure I agree). There is simply no way to punish an LLM - it isn't even clear what that would mean punishing. The weights file? The GPU that ran the weights file?
And on the "controls" front (but unrelated to the above note about memory) LLMs are fundamentally only able to manipulate whatever computers you hook them up to, while people are agents in a physical world and able to go physically do all sorts of things without your assistance. The nature of the necessary controls end up being fundamentally different.
Rather more sophisticated Retrieval Augmented Generation (RAG) systems exist.
At the moment it's very mixed bag, with some frameworks and harnesses giving very minimal memory, while others use hybrid vector/full text lookups, diverse data structures and more. It's like the cambrian explosion atm.
Thing is, this is probabilistic, and the influence of these memories weakens as your context length grows. If you don't manage context properly, (and sometimes even when you think you do), the LLM can blow past in-context restraints, since they are not 100% binding. That's why you still need mechanical safeguards (eg. scoped credentials, isolated environments) underneath.
Limited space to work with, highly context dependent and likely to get confused as you cover more surface area.
If a junior fucks production that will have extroadinary weight because it appreciates the severity, the social shame and they will have nightmares about it. If you write some negative prompt to "not destroy production" then you also need to define some sort of non-existing watertight memory weighting system and specify it in great detail. Otherwise the LLM will treat that command only as important as the last negative prompt you typed in or ignore it when it conflicts with a more recent command.
The LLM did have this capability at training time, but weights are frozen at inference time. This is a big weakness in current transformer architectures.
Humans actually learn. And if they don't, they are fired.
The tooling that invokes the model should really define some kind of guardrails. I feel like there's an analogy to be had here with the difference between an untyped program and a typed program. The typed program has external guardrails that get checked by an external system (the compiler's type checker).
