I made an AI clone of my dead son - and let a journalist interview him

An interview between a US journalist and an AI clone of a teenager who was killed during a school shooting in 2018 has prompted criticism online.

Experts say this is one of the first times that an AI avatar of a dead person has been used in this way.

BBC Verify's Jake Horton has been speaking to the father of the teenager - 17-year-old Joaquin Oliver - and looks at the ethical questions the interview raises.
