The AI title suggestions can be a touch excitable. 
I think it’s clearly been reading too many glossy magazines in its spare time. Though I think if I could dial it down a notch it could be quite useful for topic splitting (which I appreciate is more useful to mods than everyone).
I started off quite sceptical about the use of AI for similar reasons. I’m more interested in what people have to say than how well an AI can polish it up. At the moment (and these things move quite fast) there’s also a certain tone that it generates that I think obscures/homogenises the ‘voice’ of the writer.
However, there have been a couple of Discourse AI tools that I think have turned out pretty swish. I love the Related Topics. 
That has really had an impact on how I find and engage with different topics. As an avid forum reader, this has been a treasure trove. I’ve used it across a couple of forums now, and the rabbit holes of connected content I’ve lost myself down have been amazing. Also really great for finding answers and linking up topics as well.
Bert, the AI Bot, has also been brilliant. Especially now he has SQL Helper and Site Setting personas. I think these are more geared towards the admin side (and maybe my job ), but he’s been a real boon 
(and I think we may actually be friends )
I think what has won me over is how useful using the AI-based tools to help out with the everyday stuff has been. I still don’t think I’d want an AI filter on the contributions themselves, but having ‘clever’ helpers has certainly made my life easier, and allowed me to focus more on the things I like doing.
