> How do junior developers level-up to get into private Slack spaces? Where do they learn from if Stackoverflow is hostile, Reddit is hollowed out, and social squares are empty?

Books seem to still work very well. I am not even sure all this social media learning was that much positive. A lot of it was based on trend chasing, shiny object syndrome and stuff like that in a completely a-historical context. It was always funny when some star social media coder re-discovered something that probably people did in mainframes before I was born and that you can find in a lot of books.
