The Floating Friend

Andrew kicked a pebble down Maple Street, watching it bounce off the cobblestones. His smartwatch beeped with another notification about weird computer glitches around Sunnybrick Town. The third one this week.

"This is getting strange," he muttered, adjusting his backpack straps.

A shadow fell across the sidewalk. Andrew looked up, expecting a cloud, but saw something impossible instead. A perfectly round, black sphere floated three feet above him, about the size of a basketball. Two enormous silver eyes blinked down at him.

"Um, hello?" Andrew said.

The sphere bobbed once, like a nod.

"Are you... an alien?"

Another bob.

Andrew's mind raced. This was either the coolest thing ever or he'd finally cracked from too much coding. "Can you talk?"

The sphere just stared with those huge, unblinking eyes.

"Well," Andrew said, "want to see something cool? I've been tracking these computer problems around town. Maybe you can help me figure out what's going on."

The Bakery's Secret Screen

Andrew pulled out his tablet and showed the floating black sphere his tracking map. Red dots marked three computer crashes around town this week.

"See? First the library, then the school, now the pet store," Andrew said. "Something's messing with their systems."

The sphere bobbed and suddenly vanished.

"Wait, where did you—"

Andrew blinked and found himself standing inside Sunny's Bakery. The warm smell of fresh bread filled the air. Behind the counter, Mrs. Chen was showing her teenage daughter Lucy something on a computer screen.

"Our new ordering system learns customer preferences," Mrs. Chen explained. "We feed it thousands of examples—'chocolate chip cookies ordered on rainy days' or 'birthday cakes requested two weeks ahead.' The computer finds patterns and suggests what people might want."

Lucy frowned at the screen. "But why is it acting weird today? Look, it keeps suggesting fish sandwiches to everyone."

Andrew stepped closer. The screen flickered, showing scrambled data. Something was definitely wrong with the learning system.

"That's exactly like the other crashes," Andrew whispered to the sphere, which had reappeared beside him. "Someone's messing with how these computers learn."

What we learned: AI models learn by processing massive amounts of data, like showing a computer millions of pictures to teach it what a cat looks like. Machine learning requires labeled examples, like photos tagged "dog" or "not dog" to teach the computer.
