I’m leaning in this direction too. I saw someone on Twitter phrase it quite well: “You can believe that most jobs are bullshit [jobs]. And you can believe that GPT-4 will completely disrupt the job market. But you can’t believe both.”
But upper management can know exactly what LLMs are capable of, because they are products with fixed capabilities. ChatGPT is the same ChatGPT for everybody. This makes firing obsolete workers much safer.
