Its true it seems that millennials is less educated and probably the worst generation where even in social media their post are annoying they're main concern in life is sex, drugs and alcohol. They spend more time in online games, burning their money doing meth & alcohol and social media than spending more time in productive skill development or investing their futures into something like crypto.
It will be wrong to label an entire demographic group like this. Although I would agree with some parts of your post, I have to say that many of the millennials are even more skillful than the older age groups. I am working in the IT industry and many of the millennials who have recently joined my company are very knowledgeable in coding and programming.
In my opinion, while in the world there is an opportunity for each person to realize himself, there will be a balance between those who are smart and work on the development of our society and those who burn not only their money, but their whole life, without thinking about the essentials and future. but nonetheless, whether humanity does not destroy itself, then the natural process will do it for us. Its even possible to take Global Warming as an example.
As for the Millennials, the enthusiasm of this generation for digital technologies is just a tribute to fashion, because in those years there was a real explosion of the development of advanced technologies. And today, almost no one is surprised by this.
