Today's software ecosystem evolved around a central assumption that code is expensive, so it makes sense to centrally develop and then distribute at low marginal cost.
If code becomes 100x cheaper, the choices no longer make sense! Build-buy tradeoffs often flip.
The idea of an "app"—a hermetically sealed bundle of functionality built by a team trying to anticipate your needs—will no longer be as relevant.
We'll want looser clusters, amenable to change at the edges. Everyone owns their tools, rather than all of us renting cloned ones.
