Yeah, same here. I'm not going to stop using em dashes, or, like, sentences. I will not introduce deliberate mistakes (I make enough anyway). I'm not going to participate in any snake-oil 'human certification' schemes. AI is like eating broken glass: it's not something tempting I have to resist.
Rien GrayAI is not producing anything like my work so I don’t fear this at all, really! And I love em dashes plenty.
