Look at these AI-generated faces:

On the internet, you can meet false persons that claim to be your friend with false images generated by a machine. In the worst case, you can be talking to a machine on Facebook.
People have to visit their friends in real life and not sit so much on the internet.
They probably can make a false video of people too on the internet that somebody do something wrong like a crime or sin, while the real person did not do it.
Technology has gone too far now and more advanced will it be in the future.
Also, they can print out DNA and make clones out of people and make a new person.

Mirage sound like a mirror:
An example is found in this link: https://i2.wp.com/www.lasvegas360.com/360/wp-content-lasvegas360/uploads/2015/05/The-Mirage-Hotel-Las-Vegas-2012.jpg
One building mirrors itself on both sides of the center. A mirage in the desert is that you see an oasis with palm trees and water/lake, an image of what your mind is longing for. It is an optical phenomenon in the air because moist and heated air makes what some would call a “Hallucination” because you can walk forever towards an oasis and then only find sand.
Then I think we have money mirages, building mirages, and information mirages.
