These prompt injection vulnerabilities give me the heebie jeebies. LLMs feel so non deterministic that it appears to me to be really hard to guard against. Can someone with experience in the area tell me if I'm off base?

I think a nice compromise would be to restrict agentic coding workflows to cloud containers and a web interface. Bootstrap a project and new functional foundations locally using traditional autocomplete/chat methods (which you want to anyway to avoid a foundation of StackOverflow-derived slop) then implement additional features using the cloud agents. Don't commit any secrets to SCM and curate the tools that these agents can use. This way your dev laptops are firmly in human control (with IDEs freed up for actual coding) while LLMs are safelt leveraged. Win-win.

I have to check what junior engineers do before running it in production. And AI is just really fast junior engineering.

The really fast part is the challenge though. If we assume that in pre-LLM world, there was enough resource for mid/senior level engineers to review junior engineer code and then in LLM world, lets say we can produce 10x the code, unless we 10x the number of mid/senior level engineering resource dedicated to review, what was once possible is no longer possible...

A problem yes, but I think GP is correct in comparing the problem to that of human workers. The solution there has historically been RBAC and risk management. I don’t see any conceptual difference between a human and an automated system on this front

Well, perhaps not worthless, but certainly not "a trillion-dollar revolution that will let me fire 90% of my workforce and then execute my Perfect Rich Guy Visionary Ideas without any more pesky back-talk."

That said, the "worth" is brings to the shareholders will likely be a downgrade for everybody else, both workers and consumers, because:

> The market’s bet on AI is that an AI salesman will visit the CEO of Kaiser and make this pitch: “Look, you fire 9/10s of your radiologists [...] and the remaining radiologists’ job will be to oversee the diagnoses the AI makes at superhuman speed, and somehow remain vigilant as they do so, despite the fact that the AI is usually right, except when it’s catastrophically wrong.

> “And if the AI misses a tumor, this will be the human radiologist’s fault, because they are the ‘human in the loop.’ It’s their signature on the diagnosis.”

> This is a reverse centaur, and it’s a specific kind of reverse-centaur: it’s what Dan Davies [calls] an “accountability sink.” The radiologist’s job isn’t really to oversee the AI’s work, it’s to take the blame for the AI’s mistakes.

Security shouldn't be viewed in absolutes (either you are secure or you aren') but more in degrees. Llms can be used securely just the same as everything else, nothing is ever perfectly secure

I'm not saying IBM shouldn't try, but really – why is IBM building coding CLIs? They're like the company version of the Steve Buscemi "How do you do, fellow kids?" meme.

I saw an IBM presentation about AI at a conference years ago, during the previous wave of AI hype (2018-ish). IIRC they were advertising some specialized AI chip/hardware. The presentation was kind of meh, but it shows they've been trying to dab in this space for a while.

You would think so, but you should read about how they bear proof trash cans in yellow stone.

They cant. Why? Because the smartest bear ia smarter than the dumbest human.

So, these AIs are suppose to interface with humans and use nondeterminant language.

That vector will always be exploitable, unless youre talking about AI that no han controls.
