Bizarrely, the post on Marginal Revolution links to a post from 5 days ago, and it's easy to confirm that Jake was still alive when that post was published. (And, apparently, for almost a week afterwards.) The gofundme appears to be the only source that states he's died, and the MR report doesn't even mention it. (Other than to include a link to it in a quote from someone else.)
