The tools very commonly don't work as advertised tho, but people still buy them because of the incredible promises of increased efficiency. And since it's usually not easy to measure, they keep paying, sometimes companies even force their employees to use it.
It's an even bigger grift from the POV of companies building AI into their products - investors pressure companies to add AI features, managers demand thing that aren't achievable, developers bodge things together because they know it's worthless, marketing sells it like it's perfect, customers don't actually want it so sales bundles it into every plan and increases the price. Number go up, everyone gets a promotion. The customer has no alternatives because everyone else is doing the same.
