It is probably a good trade off if you sell cookies or if you vastly prefer eating cookies to making cookies.

Sure, and that probably explains why companies (who sell software) love AI while hobbyists who just like to program hate it.

For the owner/shareholders yes.

The workers will see the fun evaporate but now they have to clean 10x cookie trays in the same 8 hours.

It is, although in this case the cookie-making robot also makes 10% of its cookies with sand instead of flour. So it's still not a very good trade if you have any pride in your business or consequences for bad product.
