Is it more fashionable to build an AI harness?

I genuinely have no idea what this comment is about. Why is a to do list a bad example? It's common precisely because it's ideal: it shows a few different basic widgets, and it shows how to update state in a way that keeps them in sync.

Is it because it's clichéd? That doesn't matter so long as it gets the point across.

Is it because you object to having desktop applications that do a simple task like this? I remember when simple single-purpose desktop apps were common e.g. Card File in Windows 3.1. Also this is meant to be an example for both desktop and mobile. Are only SPA web pages allowed to do things like this now? What a depressing world if so.

Or is your comment satire? I honestly can't tell.

Edit: What would you allow as a first example of a new UI toolkit. (Not that Flet is new, it's had plenty of 0.x releases.)

Why?

They didn't even show a prompt box with starry icon button!

It's one of the standard benchmarks for web frameworks.

No clue why it's being done here.

Specially one looking so bad.
