Ffs, I had one of those at work.
One day, we bought a new water sampler. The thing is pretty complex and requires from a licensed technician from the manufacturer to come and commission it.
Since I was overseeing the installation and later I would be the person responsible of connecting it to our industrial network, I had quite a few questions about the device, some of them very specific.
I swear the guy couldn't give me even the most basic answers about the device without asking chatgpt. And at a certain point, I had to answer myself one question by reading the manual (that I downloaded on the go, because the guy didn't have a paper copy of it) because chatgpt couldn't give him an answer. This guy was someone hired by the company making the water sampler as an "expert", mind you.
