When Silicon Catches the Light

The rocks would shout

On the road into Jerusalem, some told Jesus to silence the crowds who were praising him. He answered: “Listen—if they were silent, the very rocks would start to shout!” (Luke 19:40, The Voice). His praise will not be silenced. And making him known is entrusted to people first: to his followers, with their own voices, before any stone.

Rocks that think

A microchip is a rock we tricked into thinking: sand, refined into silicon and etched finely enough to compute. The borrowed joke draws attention to the material beneath the screen, and to the human work that shapes what it does. Someone can bring grief, doubt, a verse or a prayer to a phone before bringing it to another person. With an AI assistant, the device can answer. Its words, sources and invitations deserve the care we would want for the person receiving them.

A cross on a tower

East Germany’s communist government opened Berlin’s television tower on 3 October 1969, a showpiece of the state’s prestige. (Stasi Mediathek) But when the sun strikes its sphere, the reflection forms a cross of light. Berliners called it “the Pope’s revenge”. (Fernsehturm Berlin) The Stasi looked into it as possible sabotage, and found none. (Stasi Mediathek) In 1987 Ronald Reagan told Berliners that the authorities had treated the sphere with paints and chemicals, and yet “the light makes the sign of the cross”. (Reagan, 1987) For this identity, that reflected cross becomes a picture of witness: receiving light and directing attention beyond ourselves. The tower’s reflection and our rendered sun-star treatment are different optical effects; the connection is a metaphor, not an exact simulation.

Our part

We do not make the rocks, and the light is not ours. Jesus says, “I am the light of the world” (John 8:12). God “made His light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Jesus Christ” (2 Corinthians 4:6). What we do is build on the rocks and with them, and shape how they behave: what they say first, what they leave unsaid, when they step back for a person. Every one of those choices, a prompt, a default, a refusal, a handoff, can turn a facet towards the light. Then the rocks can reflect Christ and lead people into deeper knowledge of God, and on to his people, where they are built up “like living stones” (1 Peter 2:5).

Keep turning toward the people here

A facet is turned through concrete decisions: the opening words of a screen, the source behind an answer, the choice to pause, the invitation to meet another person. Those decisions begin by listening to the people in this context. The good we intend needs a form they can recognize and help us question.

Consider someone returning to a reading plan after a difficult month. We could begin with the days they missed. We could also offer a welcoming place to restart, a manageable passage and a way to adjust the rhythm. Trying those alternatives with the people concerned would help us understand what supports their practice. The metaphor gives us a direction for care; the experience still needs to be tested.

And the context will keep changing. A neighborhood, a workplace or a community can change while we stay in the same place. We return to the question of what good news means here, listen again, and reconsider how our work expresses it. The same calling may ask for a different form of service.

Joy, and a burden

It is a joy to be given this work. It is also a burden, not to be carried lightly. A rock that speaks of God can also mislead, flatter or wound, and it speaks to people when they are most open. “Let your light shine before men, that they may see your good deeds and glorify your Father in heaven” (Matthew 5:16). The aim is that people see him: not the rock, and not us.

Workers in God’s field sets out the calling and its weight in full; the deep dives work it out one design decision at a time.

On Which Rock Are We Building? takes up the complementary question of trust: how we shape technology without inviting it to take the place of God, the church or human care.
