Anecdotally, my partner does experience design for fintech systems akin to Bloomberg for a particular niche. They do the standard lifecycle of user research, design iteration in figma, handoffs to devs and all that. The tech department at this company has also been building OpenAI integrations for more than 2 years and are neck deep in LLM technology doing exactly what this thread describes. My partner is still doing exactly the same work she's been doing the entire time and getting the same level of adoption for all the bespoke UI development while the chat interface is just kinda there. I'm sure it's getting usage for some tasks, but it's supplemental.
