The App Store might seem like low friction relative to installing software to your PC from a CD.
But it's still massive amounts of friction.
Some of that friction is for the user of installing, and then putting relevant data into the app, since it's a silo.
But a lot of that friction is hidden from the user, in the forms of the sisyphean tasks a developer has to do to even create an account to get apps in the App Store.
This friction must be there because in the current physics of trust, software is dangerous, and so there must be friction to avoid harm.
The friction means that only maybe 10% of the useful software that could exist does exist.
We're so used to software having to be trusted, so needing significant distribution friction, that we can't imagine any other way.
But with different physics of trust, there could be an order of magnitude more useful software.
