Writing is one of the most accessible forms of expression. We were living in a world where even publishing was as easy as imaginable - sure, not actually selling/profiting, but here’s a secret, even most bestselling authors have either at least one other job, or intense support from their close social circle.
What you do to write good is you start by writing bad. And you do it for ages. LLMs not only don’t help here, they ruin it. And they don’t help people write because they’re still not writing. It just derails people who might, otherwise, maybe start actually writing.
Framing your expensive toy that ruins everything as an accessibility device is absurd.
