I've never tried to have what I would call a conversation, but I use it as a tool for both fixing/improving writing and for writing basic scripts in autohotkey, which it's fairly good at.
It's language models are good for removing the emotional work from customer service - either giving bad news in a very detached professional way or being polite and professional when what I want is to call someone a fartknocker.
The closest I come to chatting is asking github co-pilot to explain syntax when I'm learning a new language. I just needed to contribute a class library to an existing C# API, hadn't done OOP in 15 years, and had never touched dotNet.
I ask additional questions or provide information from my side to get a better answer, but I'm still doing this to solve a problem or gather knowledge. I guess that counts as a conversation, but not a casual one.
I forgot how the conversation went, but one day, a conversation I had with someone about comprehensibility (which was often an issue) compelled me to talk to an AI, a talk which I remember from the fact the AI did now have such issues as the complaining humans had.
Yeah I’ve run into this a bit. People say it “doesn’t understand” things, but when I ask for a definition of “understand” I usually just get downvotes.
Not as much as I did at the beginning, but I mainly chalk that up to learning more about its limitations and getting better at detecting its bullshit. I no longer go to it for designing because it doesn't do it well at the scale i need. Now it's mainly used to refractor already working code, to remember what a kind of feature is called, and to catch random bugs that usually end up being typos that are hard to see visually. Past that, i only use it for code generation a line at a time with copilot, or sometimes a function at a time if the function is super simple but tedious to type, and even then i only accept the suggestion that i was already thinking of typing.
Basically it's become fancy autocomplete, but that's still saved me a tremendous amount of time.
