The real "white-collar massacre" is not caused by AI, but you have no irreplaceable, or the value created by hiring you is not higher than using AI. Businesses will not hesitate to use AI, you can't say that companies are ruthless, but that's the pursuit of efficiency. Just as horse-drawn carriages were replaced by cars and coachmen lost their jobs, you can't say it's a problem with cars.
History is always strikingly similar, the AI revolution is the fifth industrial revolution, and it is wise to embrace AI and collaborate with AI as soon as possible.
There's a popular saying, e.g. used by NVIDIA CEO Jensen Huang, that "AI won't replace you - a human using AI will replace you", which may be temporarily true while AI isn't very capable, but the AI CEOs are claiming AGI will be here in 2 years, and explicitly saying that it will be a "drop-in replacement remote worker". Obviously one of these is wrong - it's either just a tool to be learnt and used, or it is in fact a drop-in replacement for a human.
One can argue about the timeline and technology (maybe not LLM based), but it does seem that human-level AGI will be here relatively soon - next 10 or 20 years, perhaps, if not 2. When this does happen, history is unlikely to be a good predictor of what to expect... AGI may create new jobs as well as detstroy old ones, but what's different is that AGI will also be doing those new jobs! AGI isn't automating one industry, or creating a technology like computers that can help automate any industry - AGI is a technology that will replace the need for human workers in any capacity, starting with all jobs that can be conducted without a physical presence.
