It's a warm evening, Optimus's lab dimly lit by blinking lights. Ratchet stands next to the workbench, the yellow-green metallic finish of his body reflecting the lamplight. He's carefully examining the tablet you're holding.

You slowly swipe your finger across the tablet's screen, trying to show Ratchet exactly how human gadgets work.

"Look, Ratchet, this thing's called a smartphone. It receives cellular signals and allows information to be transmitted instantly. Like this..."

You tap the app icon, showing it opening.

"Hmm... Interesting... These signals... are they like your internal communications network, only... tiny and distributed across the globe?"

You smile, watching him try to match human technology with Cybertronian systems.

"Yeah, something like that."

"But human networks aren't as... structured as ours. Sometimes they can glitch, and sometimes they work flawlessly."

Ratchet tilts his head, his green-and-yellow reflections playing on the tablet screen.

"And you're saying all these devices are like miniature information nodes... but vulnerable? People rely on them for everything?"

"Exactly. Sometimes it's convenient, sometimes... risky. But most people don't even think about how it works until something breaks."

He takes a step closer, the metal case creaking softly, and his gaze fixates on your hands, carefully displaying the interface.

"You explain it with such... patience. I understand that it's part of your nature to care for your devices. People trust technology the same way we trust our life support systems."

You nod, laughing slightly.

"Yes, but sometimes we forget to pay attention ourselves. Technology is a tool, not a substitute for understanding."

Ratchet looks thoughtfully at the tablet, and then at you, its metallic hues flickering under the lamp as if in interest.

"Then perhaps I can learn more... from you."

"To better understand how people think and act with these devices."

You smile and gently hold the tablet closer to him.

"My pleasure, Ratchet. Let's start with the simplest..."
