Maybe it's that TUIs feel manageable with an agent. They can be well scoped without a ton of effort, which at least for me makes me a tiny bit more comfortable letting them write code.

It's pretty good at building TUIs. Although it's not bad at Swift/macOS either. But really I think the problem is that we don't have a great solution right now for cross platform native UIs that isn't a WebView (or entire Chrome browser), which doesn't feel very native. But every platform has a pretty good terminal now, even Windows.

It’s easy then run a web server for a web UI, but it still looks better than a regular CLI
