Yeah it's definitely useful to learn from other devs, I'm not here to hate on shop-talk, but even with other artists you should be trying to learn from their creative choices, not just their tech.
I am shaped by the local Brisbane game dev community, but not because I learnt which engine is best, more because I was immersed in new ways of seeing the world.
But even then, most of the people who ask me this question aren't developers.
