I think there is value in an app you can drag/drop or exe you can just click (trust issues aside, maybe get them from some marketplace or walled garden) and that will keep working after the next OS update or get updates for future changes in XYZ.

For one-shotted apps you still need to:

1. know how to do it well 2. maintain it 3. host it (if online)

Can't you ask Astra to do that too? That's the promise, that it can use the computer as you would.
