Reads just like a consultant who doesn't understand anything about the
subject matter. :-) Listen to the people making the statement, extract
out the plausible bits (at least to the uninitiated), and repeat it back
as truth.

IOW, tell the person what they want to hear (and charge a lot of money).

The only difference is that ChatGPT hasn't yet figured out how to charge
you for reading your own watch to tell you the time...
