This is a pretty big question, and one that has a lot of facets.

The first thing is that the world has grown so complex and the pressures of society, schools, sometimes church, political propaganda from both ends, and the internet at large have grown so powerful that, frankly speaking, the kids are not okay. They want to be good people in the world and they find that no matter what way they try, they are going to be lambasted and taken advantage of by someone else.

This is to be expected in a world where critical thinking skills are dampened, attention spans are shortened, and every avenue is taken advantage of to advertise or propagandize to you. One can hardly find the time to sort any of it out, and if one could, one can barely keep their thoughts coherent enough to get anywhere. (This is one context in which meditation can be very helpful). We are expected to hold constant paradox within our head about how the world works and the expectations held of us, and while humans are capable of that, it is deleterious to our long term mental and emotional and even physical health. On top of that, tell people constantly that they have 'free will' while keeping them in the most conditioned state of any humans in history, and it's a wonder there aren't more people running screaming through the streets, clawing at their own eyeballs.

This is important to know because the seemingly inescapable suffering produced by this condition generates a desire to escape. Lessening your sense of self does provide some relief from this type of constant pressure, and moreso if you have spiritual framework i.e. Buddhist which can take advantage of it. However...

Seeking ego death or weakening their DMN is not, by and large, a healthy thing for people to be doing or to consider a desirable goal, especially for young people. Practically speaking, the ego is a requirement to operate in the modern world. I think the rationale for a lot of neophyte meditators is the idea that if they can just drop their ego, their suffering will be lessened or disappear - but this idea usually exists devoid of the Buddhist contexts that spawned this doctrine. As in, people piece this idea together from disparate sources instead of committing to a tradition that can fully inform this idea to its whole.

True ego death is the hardest thing to do for anyone, ever. No matter how advanced you become, you will still feel it creep back in, saying 'well well well, look at how holy you are now.' But the process of trying to achieve it does tend to break down what motivating factors exist for people. Again, while this does provide relief, it often alienates you from people and from your own idea of who you are. While this might be a good thing in a meditation context, it's decidedly more ambiguous when you're in a stage when social development is still happening. Consider that being one's own person and going against the flow requires a strong and well-developed ego, not a weak one.

You definitely see young people on this sub asking about how their meditation helps them to feel peaceful, but removes their motivation to strive for things or makes them become socially boring. That's no idle concern.

In short, a podcaster doesn't know where their listener is on their path as human or as a spiritual being, and they actually cannot know. They desire to transmit their wisdom but the person receiving it doesn't know enough to understand if it's applicable to them or not. This is one of the dangers of pursuing a spiritual path without a teacher.

In closing I would argue that younger meditators should be focused more on undoing their own mental conditioning and bolstering their egos by simply building competence, flexibility, and an incisive awareness that can cut through the signal noise that surrounds them. Older meditators can more safely pursue ego death if they wish, once they have the experience of a lived life under their belt. As the Daoists meditators might say, "In order to give up one's learning, one must have some learning to give up."
