Kind of. But you can see boredom as the desire for novelty, a cue to find something new so we can get that dopamine hit. Phones, internet and media are fantastic at giving us that little kick to keep us going, so we don't feel the need to engage our brain in more useful ways. Without that easy access to the dopamine treadmill that is your phone, you are encouraged to seek novelty elsewhere. This might be in wandering thoughts, seeking interaction with people or things around you, or some other endeavor.

To think a little further forward, doing this tends to increase the time until the next novelty, so you get practiced in not constantly seeking immediate gratification. It helps increase your ability to be patient and to concentrate, which in part is the ability to not switch tasks at the first hint of boredom.

I would put it as, we've forgotten how to not be distracted. The mind needs time to wander.

He meant we can't stand to be bored anymore. At the slightest chance we immediately look for distractions, like the internet.

I agree with this but would emphasize that this is just an exercise to get free from a distracted state in your mind all the time.

I feel like this is a common semantic disagreement.

Some people want to encourage disconnecting yourself from external stimulus, and just enjoying your own thoughts, and use the word "boredom" to describe this. Whereas other people feel that "boredom" means the frustrating state of being entirely unengaged.

I sometimes wonder if people who don't disconnect very often haven't experienced much of the latter kind of boredom, and so aren't as aware of it as a negative thing.

Boredom is the state of not being satisfied with any of the sources of reward currently available in your environment.
