At the (tail) end of 2024, Billie Eilish sat cross-legged on stage and began to miaow. Her fans erupted in harmony, each belting out an off-key miaow of their own. This is because Eilish's Oscar-winning track What Was I Made For? – a lachrymose Barbie cut lamenting adulthood's entailing ennui – has become the default soundtrack for a new breed of cat video.

Billie Eilish has fielded countless interview questions during her meteoric rise to fame, but this week was the first time that they've been asked by a bot.
