Make Bitdevs meetups more young people friendly. You can do all you want online but expecting to be on the same wavelength as the kids is just not likely gonna happen. Find Bitcoin, or even Blockchain student clubs, and get them to sponsor Bitdevs providing meetup spaces. They feel included -- as leaders even -- and it attracts the older developers in the region to meet in meatspace and cross pollinate ideas. I see a good few younger folks at the ones hosted at MIT. Yea, it's MIT, so it's a bit easier, but still it gets us all in the same place so the veterans can share experience, we non-devs can share our take on philosophy, economics, etc (and learn a thing or two), and the kids can share their understanding of some new innovative ideas and some fast moving developments that can be hard to keep up with when you're working full time with a family. Bonus, doing it with blockchain clubs can convert them from the inside as the real differences are laid bare to be seen for all.
