Like all automations it's not 100% perfect, and they all require a human to monitor them.
Turning over a problem to a LLM as solved means we won't be able to do the task anymore. Because we will never learn how. We will not know that the LLM has made a mistake, and will be unable to fix it ourselves.
Right now we can correct the LLM, as the years go on we will become unable to do so.
