LLMs are more like a trench digger with a cat's personality. It can helps in some cases, but are more likely to destroy a field. And good luck if you have some difficult terrain to pass through.
The others also may contain wrong information, but the risks are lower and not being automated means the risks are not compounded.
I personally believe we need more trustable source of information rather than automated way to transform it. Especially for the low hanging fruit of coding, which still require to presolve the problem and put us back at the real reason to have a developer.
And one thing that people seems to forget is the wealth of pre-LLM tools to speed up coding. No one uses notepad (from Windows 7) to write code, which is what they keep brandishing as the alternative to their agents and what not.
