Srilanka, Feb. 13 -- YouTube is flooded now with videos made using artificial intelligence.There are music videos of world leaders singing or playing instruments, with other presidents and prime ministers in the audience.One video shows Russian President Vladimir Putin playing a guitar and singing a 90s American pop hit as world leaders such as Donald Trump and Narendra Modi sit in the audience, laughing and cheering. I noticed that the lip synch was sometimes out, but it looked very convincing.

Another showed Donald Trump and Kim Jong Il sitting together and playing a traditional string instrument, again very convincing. All this may look like good fun, and this artificial intelligence 'make believe' world isn't just limited to music....
