Question

How might society have been most likely impacted if Nikola Tesla, the inventor of AC technology, had not become a scientist?

DDT might have never been used.
People’s homes might not have been built with electricity.
Polio might have made thousands of people sick.
Plastics might not have been invented.

Answer 1

"People’s homes might not have been built with electricity."

Tesla’s work on alternating current (AC) generation, transformers, polyphase motors and transmission systems was central to making long‑distance, practical electrification possible. Without him the adoption of AC distribution would likely have been delayed (others could eventually have developed similar solutions, but more slowly), slowing household electrification.

The other items are unrelated to Tesla: DDT and plastics were chemical inventions by other scientists, and polio’s impact depended on virology and vaccine work decades later.
