Besides probabilistic and non reproducible output, programming languages are designed to be unambiguous and explicit, and human language doesn't have that.

For(){} it's normally either undefined or has a specific meaning. "Then iterate and do x" might mean many subtly different things.

Most programmers never deal with a compiler bug in their whole career, and can dismiss the possibility. For LLMs it would be hard to even define what a "compiler bug" would be since there is no specification for English.

Then there's the fact that models generally don't guarantee anything at all. Sonnet can change under your feet.

Models also degrade as the context window gets larger. Compilers handle one line just the same as 20.

I could keep going, there's so many fundamental differences in the process that the analogy only serves to provide a false feeling of security.
