They run on an operating system you probably don't know all the inner workings of.

And that runs on a chip with trillions of transistors.

Yeah so? Claude isn't an OS. It's the thing making my code. I don't want my codebase to be some bytecode adjacent thing that LLMs operate on.

So you stand upon a big pile of black boxes.

Black boxes aren't inherently bad. But if they don't have well defined mappings of inputs to outputs, they aren't good black boxes. That's the problem with Claude Code imo.
