I know this is a silly point but imagine if this guy put the same amount of effort, inventiveness and attention to detail to some engineering or scientific endeavor. The video is great but arbitrary benchmarks in old games aren't pushing society forward as much as technological advancement can.
Besides, the sheer magnitude of difference between advancing a highly contested real life science subject versus breaking ground in an obscure challenge in a 25 year old video game is massive. I know it's not that obscure but it sure feels that way sometimes...
