> In fact, the researchers found that almost half of employees who receive AI-drafted emails see senders as less trustworthy as a result of their sending it, and over a third see them as less intelligent. So much for AI enhancing us.

Maybe it did enhance them, and maybe the assessment was correct at the same time.

There is no single effect of AI on work quality. Depends on use and effort. Use it well, it will be good, use it with close to zero effort and you'll get something distinctly better than what you could smash together manually with that much effort, but people will see that you indeed put zero effort in it, and also they will notice that you spent no effort in cleaning up AI tells because you likely can't even notice or have no idea about anything and will indeed correctly conclude you're less intelligent.

There may also be a miscalibration that's worse for people with less taste / judgment / intelligence / experience, in that it's indeed easier to produce things, but while the effort required is reduced, people expect and believe it to be reduced more than how much it is truly reduced so they overshoot and don't notice. Meanwhile, the right way to use it is to keep your usual effort level or drop it only a little, and simply produce better things.
