tl;dr it takes running untrusted code to a new level.
Since the original desire was to build any kind of personal/commercial app on an OS, the amount of potential vulnerabilities is potentially infinite.
People have always been able to slip in errors. I am confused why we assume that a LLM will on average not be better but worse on this front, and I suspect a lot of residual human-bias and copium.
