This particular professor has been teaching for 30 years. I'm not sure I find your explanation all that convincing in light of that, especially since this isn't an isolated opinion. I'm much more interested in how much the average student has had a phone to distract them during their lifetime. For the incoming 2025 class of 18 year olds, the iPhone came out the year they were born. So potentially 100%. I expect that plus the availability of LLMs is a deadly combo on an engaged student body.
