> I would’ve thought the necessity of reading in this profession obvious. But I’ve noticed a worrying trend lately: aspiring writers who don’t read.
I know it's a very bad thing to say out loud, but if even aspiring writers, those who care so much that they go to writing workshops, have stopped reading, it's a very strong signal that writing/publishing won't be a viable profession in the near future anymore.
You will be long dead before that happens.
I’m not sure your conclusion necessarily follows from the premise. There are aspiring writers who care about writing and/or publishing, and writers who care about literature. The formers usually are weaker readers. However, most of the readers don’t want to become writers.
