You're right, execs keep trying to fit the LLM square peg into the "inteligent agent" round hole.
Developers use it, for groking a codebase, for implementing boilerplate, for debugging. They don't need juniors to do the grunt work anymore, they can build and throw away, the language and technology moats get smaller.
The value of low level managers, whose power came from having warm bodies to do the grunt work, diminishes.
The bean counters will be like when does it pay for itself. Will it? IDK, IDC.
