Once upon a time, there was an ordinary man named Johnny Time. One day, Johnny Time discovered he was suddenly transported to ancient Rome with his smartphone and a power bank. However, since Johnny Time does not understand Latin, and there was no cellphone network or wifi in ancient Rome, Johnny Time was unable to communicate with the Romans. The Romans thought Johnny Time was a barbarian spy who performed witchcraft with his glowing brick and Johnny Time was arrested and had an untimely demise.
Years later, archeologists were baffled at the excavation of what appears to be parts from a modern smartphone inside ancient Roman ruins and concluded unethical companies are using the ruins as landfills for electronic waste. Thus ends the tragic tale of Johnny Time and his smartphone.
