On the personal side, I've been getting into game development, but the biggest roadblock is creating concept art. I'm an artist but it takes a huge amount of time to get the ideas on paper. Using DALLE will be a massive benefit and will let me expedite that process.
It's important to note that this is not replacing my entire creative process. But it solves the issue I have, where I'm lying in bed imagining a scene in my mind, but don't have the time or energy to sketch it out myself.
