Last week I observed how frustrating it is when an app you use is missing one feature you want.

Why don't apps add those features?

Because in software used by many people, features that only some subset of users want increase the complexity for everyone.

Software becomes the superset of all functionality used by all users.

The more powerful it gets, the more overhang of functionality for any given user, and thus complexity for most users.

Complexity is functionality a given user doesn't need or want.

In a world of one-size-fits-none software, you can't make it a perfect fit for any given user, because it would make it worse for everyone else.

But what if software was situated, perfectly personal?

Now you could have software that fits everyone like a glove.

This is now possible because software LLMs mean software in the small is no longer expensive to write.
