Spreadsheets become a rats nest as users customize them more.
Software didn't do that before because it was too expensive to create software so it couldn't change for others.
But in a world of infinite software, it's now possible.
Imagine tech support if everyone has their own bespoke app.
If software bends its will to individual users, it becomes more like prescription glasses, you can't put them on from someone else.
By default infinite software will lead to rat's nests: convex.
But if you can flip it to concave, where they build on each other as building blocks, it would be insanely powerful.
