I listen to all of those podcasts. I use them (and other podcasts) to keep me company when doing the dishes, cleaning, and other such chores. I will skip episodes if I don’t have time or if I’m not in the mood, but otherwise I listen to most of them.
The reason I listen to podcasts is that it’s a low-effort way for me to learn, and I can combine it with doing other things. It’s mostly about hearing the perspectives of other developers - even if I don’t agree with them, I usually pick something up, or nuance my own thinking on some subject. And the banter is always fun.
Does Not Compute is another podcast that could be added to the list. It’s not Elixir-specific, but the hosts mention Elixir quite a bit, as they both use Elixir for their work. Basically they use the podcast to chat about what they’re doing at work, challenges, successes, learnings, etc. Lately they’ve been talking a lot about PHP and Laravel, and contrasting those to Elixir and Phoenix - a discussion I have enjoyed, as the hosts have a very pragmatic attitude.
