A lot of jobs don't need a human for anything from 80-99% of their work tasks and can be replaced by an LLM or other form of AI/ML. As an employer, you hire the human for the 1-20% where you actually need the experience - to quote the punchline of an old but gold joke [1]:

In many a company, the "old neckbeards" and "dead weight" are the first ones to be cut or eventually be driven off by ever more outright bullshit - and often enough, it is only realized way too late that important "institutional knowledge" is gone [2].
