One year, 41M digits: How Luke Durant found the largest known prime number

I understand some negative comments here, that this was somewhat pointless waste of money. But I would argue that him spending 2M$ is in the same category of people spending money to do climb a mountain nobody did climb, or beat world circumnavigation record etc. I.e. this is a bit of hunt for glory. And in some sense it's not the worst one.

wait until people hear about research grants
