Some technologies come to the world as curiosities, others come as alarms and the new application from the Los Angeles company 2Wai definitely dreams of the second case, the startup went viral presenting something that many people dreamed of and that many people also fear.

Interactive digital avatars that recreate the appearance, voice, even behavior of deceased relatives, it is a future that is reminiscent of movies, but that is suddenly here, the demonstration that shook social networks begins with a pregnant woman conversing with the digital version of her mother, already deceased.

Months later, the avatar appears reading stories to his baby. Years later, he talks to the child upon returning from school and the sequence ends with the adult son announcing to the digital grandmother that she will become a great-grandmother, all on the cell phone screen, all with a disturbing naturalness, “3 minutes can last an eternity, says the company's video.

One of the co-founders of the company 2Wai went even further by stating that the platform is building a living archive of humanity and completed the provocation, “what if the loved ones we lost could be part of our future”, the idea is now available in the App Store, the application creates what they call an avatar, a digital recreation that looks, speaks and even shares past memories without the data provided by the users.

It's a kind of interactive legacy or as some critics said, a technological way of rejecting the ending, the parallel with Black Mirror was immediate, especially in the episode Be Right Back, in which a woman digitally revives her deceased partner.

Specialists warn that this can confuse memory, attachment and the natural process of grief. After all, what does it mean to move forward when technology offers a digital version that never disappears? And who decides how faithful that avatar is to the original or when it stops being?
