>or there is a more deliberative approach to assigning credit than who was "first" to solve some problem

it feels like an unintended consequence of the millennium prize is that people view the [last contributor to the solution] as the only one to make progress on the problem. I've never viewed Poincaré as solved by one person and the objective of the prize was to encourage more people to make attempts and contribute towards progress.

this issue is independent, but in these circumstances perhaps interweaved, with the 'ai is taking over math' concerns
