Honestly, this question came up in the panel too, and the way the speakers put it really clicked for me. When it comes to UAT and use-case testing anything that involves real human behaviour AI can help a lot, but it’s not something you hand the entire responsibility over to.
Think of AI as your amplifier, not your replacement. It’s great for doing the heavy lifting: generating tons of realistic scenarios, replaying user sessions, analysing patterns, even simulating user traffic to see how your product holds up. That part, AI does brilliantly and at scale.
But the moment you step into areas like “Does this flow feel natural?”, “Will a user actually trust this step?”, or “Is this accessible and comfortable for everyone?” that’s where humans still matter the most. No model today fully understands emotion, trust, frustration, or those tiny UX decisions that shape a real user’s experience.
So the takeaway for me was this: Use AI to speed up and expand what you can test, but keep humans at the center for subjective judgement and the real-world nuance UAT demands. It’s a partnership AI handles the scale, humans handle the sense.
