Yeah, I don’t get the snark. Science is about asking and answering such questions.

From a strictly scientific standpoint, it is an interesting question.

Trust me, Adele’s career will be fine. The fact that Rihanna is still a thing after her previous lead up singles did nothing and the lukewarm acceptance of her new album hasn’t gone over well, shows no one missed her IMO.

If it’s your job to do a performance you agreed to do and you don’t have mitigating circumstances ie illness, family issue , then yeah, I can blame her to just not wanting to work.
