I knew adding that might raise some hackles.
I'm not anti-LLM, in fact I use them heavily. It might surprise you to know I've even used them to write cold emails. My issue is not with cold emails but with the deception. I'm always 100% upfront about what I'm selling and I also don't let a LLM loose with my email. It's written emails but I've sent each one, by hand, normally after some heavy editing.
I think there is a way to use LLMs without being gross about it.
You could've written those emails by hand, it would've just taken you longer. The kind of spammer you're talking about it couldn't do it, the effort bar is too high. To me it seems that the net benefit is negative.
