I'm not too in touch with what kids want these days, but who would have expected 40 years ago that vinyl would be outselling CDs by now? Things go in cycles and it's hard to second guess what is next. Kids have access to so much stuff through their phones now, but will still go to a cinema to see the latest Marvel movie on a big screen. That industry had a bit of a revival too.
I really don't who where things are with comics. I just buy a few books since I got into them recently. Only a couple are by Marvel. The writes, artists and industry in general need to figure out where their market will be in future. Obviously you need to be online to even get seen, but some will still want physical media.
Interesting times.
People will always want physical media, you can't live a life only surrounded by nothing but sd cards and jumpdrives, haha. The media that stays relevant will be the media that is fun and appeals to people.
I think young people have a different attitude to how they consume media. They are used to downloads and streaming for everything. They may be happy to 'own' stuff that is 'in the cloud'. This is where blockchain may win as it does give some real ownership, but it's still evolving.
