With a diminished ability to store, recall and thus manipulate information, our learning is arguably more shallow.

With AI trained on increasingly generic input used by the casual, then the quality of our production will increase in quantity but decrease in quality.

But the disadvantages--which will be overlooked by the young and those happy to have a time-saving tool, namely the majority--will do harm, harm most will overlook favouring the output and ignoring the atrophying user.
