As a ham radio operator (KA9DGX), I tend to view all of this through the lens of impedance matching, it's my metaphor of choice.

You could use a badly designed antenna with a horrible VSWR at the end of a coax, and effectively communicate with some portion of the world, by using a tuner, which helps cover up the inefficiencies involved. However, doing so loses signal, in both directions. You can add amplification at the antenna for receive (a pre-amp) and transmit with more power, but eventually the coax will break down, possibly well before the legal limit.

It is far better to use a well designed antenna and matching system at the feed point. It maximizes signal transmission in both directions, by reducing losses as much as possible.

A compiler matches our cognitive impedance to that of the computer. We don't handle generating opcodes and instruction addresses manually very well. I don't see how an LLM is going to do that any better. Compilers, on the other hand, do it reliably, and very efficiently.

The best cognitive impedance matches happened a while ago, when Visual Basic 6 and Delphi for Windows first came out. You might think LLMs make it easier that that, but you'd be mistaken, for any problem of sufficient complexity.
