1Not long ago, chatbots could only answer a few simple questions from a fixed list.
2Today, artificial intelligence allows them to hold surprisingly natural conversations with millions of users around the world.
3Banks use them to help customers check their balances at any hour of the day or night.
4Airlines rely on them to rebook thousands of flights when bad weather causes sudden delays across the country.
5Students even ask chatbots to explain difficult concepts from their textbooks in simpler language at home.
6However, these systems sometimes produce answers that sound perfectly confident but are completely wrong in reality.
7For that reason, experts warn that people should always verify important information from other reliable sources.
8There are also growing concerns about jobs, as chatbots gradually replace some human workers in many offices.
9Supporters argue that the technology actually frees people from boring and repetitive daily tasks at work.
10The truth probably lies somewhere between the darkest fears and the brightest promises of both sides.
11What seems almost certain is that chatbots will soon become a completely normal part of daily life.
