And all expectations settled into silence,

In the 17th century, they started using oil from sperm whales to make candles that were harder and smelled less when burning.

They also made candles from cow fat, and in Korea, common people used oil from perilla seeds and cotton wicks for their lanterns.

Humans have spent thousands of years trying to find and use the right hydrocarbons.

Improvements were made to fit the situation and level of technology at the time.

And no matter how much you improve a filament light bulb, it can't become a fluorescent light.

And no matter how much you improve a fluorescent light, it can't become an LED light."
