That's like saying machines are bad because people still hand excavate ditches in the last couple feet near utilities. You are missing the point. Anyone who can do the full job isn't missing anything by skipping the drudgery.
Every task the AI can juggle for you is one you don't have to. If your department goes from 4 to 3 great, if it goes from 2-1 or 1-0 that's fine too. Companies already exist at those numbers. You can think about it in terms of "a company can now be bigger before they need a dedicated person/team for job X" if that helps take the emotion out.
There's zero emotion, no need to manipulate via injecting language like that.
Companies that can benefit from these sorts of purchasing use cases don't exist at 0. And at 1, this is already a minimal need so not useful. Past 2, and you need 2 staff anyways from reasons listed and more, so AI doesn't give a cost benefit, but it does introduce all kinds of risk (there's a lot more than just comparing SKUs) and weaken relationship with supplies, which can kill a company. Just doesn't make sense all around.
