The Disadvantages of the Fields Medal

The Fields Medal is only awarded once every four years and it's only awarded to mathematicians who are under the age of 40. I think originally this was intended to be a prize for promising young mathematicians as an encouragement but just for historical reasons that people who've won it has led to it becoming a much more prestigious award than maybe it was ever originally intended to be. So on some level I sometimes find it a little bit dissatisfying that Nobel Prizes are given to people really right at the end of their career often they've been retired for a long period of time. It's not selecting the sort of most exciting work you're expecting to come up with the next babies.
