UI in an AI-driven workflow

I want to get other people’s opinions on this, especially from folks in legal tech or working inside law firms. My take is that UI is going to take a pretty big backseat going forward. With AI + automation improving, it feels like a lot of legal work (pulling docs, tracking deadlines, drafting, filing, etc.) could be handled by agents running through APIs without needing much of a traditional interface. I work in automation (mainly with banks/insurance, so I get that legacy systems complicate things), but thinking about smaller or more modern law firms — if everything is connected and automated, do we really need “good” UIs anymore? Or does UI just end up being a thin layer on top? Curious what others think — especially people actually working in law firms. Is UI always going to matter, or does it start fading into the background? Part of why I’m asking is I started my career at a small shop, and this feels like it could play out very differently there vs larger firms.
