This week, Russian sociologist Alena Ledeneva imagines a future where identity documents are replaced by a song.
“Currently the world is dominated by formal procedures, taken for granted principles and top down control.
Look at the ways we are identified – passports, documents, nationalities, date of birth, family status, and profession.
Formalities are behind all of these principles. To make the world less formal we need to create alternative bottom-up identification systems – a new ID.
I suggest a song ID. After all, countries already have their anthems. A person would just need to think of their own now.
Music is that universal language that crosses boundaries – geographical, ideological and cultural.
Wouldn't it to be fascinating indeed if each person wrote one's own song ID or if it was possible to meet someone with the same ID?”
