LLMs can’t replace a single worker,
I don't think that's true, it's just not how the execs are seeing it.
If you have 100 staff using AI within the means of what it can actually do, you might not need the whole 100 staff. Maybe you only need 98 now to get the same outcome, or whatever it is.
What it can't do is replace a whole job category. You can't replace all your customer service with it, or all your developers or all your marketing team. You still need those people, but if you employ enough people in a category, eventually it could reduce how many you need, which is essentially replacing them.
