Yes, that would be great too. I think it's purely marketing and it has nothing to do with promoting science.
Actually, on the same model, they also could give 1000 $3000 prizes, that wouldn't make a very exciting press release, but I would posit it would do much more good, because it's much more likely to target someone that really needed a bit of positive reinforcement, rather than the guy that already received lots of award for an important discovery. And this is especially important in field were prizes are rare.
But now it feel like the equivalent of 7 guy/gals winning the lottery. I highly doubt it will change much in their research (if not negatively if they decide to retire) and they wont be able to invest it in other people's work, except with great difficulty or lack of agency. I fail to see where science is gaining much.
