Question

Aren’t the Efficiencies Technology Promises Good for Humanity?

Efficiency is good for some things and corrosive for others. Because efficiency is always relative to a goal, the deeper question is whether the goals our technologies make us efficient at serving are the goals that conform us to Christ.

Efficiency is not a virtue in itself. It is a relational concept — we become efficient at something. Efficient communication may help a working team, but the same efficiency applied to spiritual formation can dismantle it. Prayer, contemplation, Scripture meditation, and friendship are not efficient practices. They are slow, iterative, and resistant to optimization, because faithfulness is not the same as productivity.

Edward Tenner calls the unintended consequences of our optimizations “revenge effects” — the ironic ways that gains in efficiency produce new losses elsewhere. Email made communication faster and produced inboxes that fragment attention. Streaming made entertainment endlessly available and made deliberate engagement scarce. Christians cannot avoid trade-offs, but we can refuse to evaluate technology by efficiency alone. The deeper question is what kind of person each efficiency forms us into.

Key Takeaways: Efficiency as Means, Not End

Core Concept: Efficiency is relational — always efficient toward a goal.

Scholar: Edward Tenner on “revenge effects” of technological optimization.

Scripture: Practices like prayer, fasting, and Scripture reading are deliberately inefficient (Mt 6; Lk 5:16).

The “So What”: Christians who let efficiency drive their decisions will find their formation reshaped by velocity rather than by virtue.
