There's no Karpathy in MPLS(???) Did you mean Kireeti Kompella? His name is synonymous with BGP L2VPN (as opposed to Luca Martini, whose name is synonymous with LDP L2VPN.)
Also Andrej Karpathy was a schoolkid when MPLS was developed ;)
Huh? What Karpathy are you talking about?
Andrej Karpathy, an AI/ML researcher who does a lot of education and public outreach. I don’t know the answer to GP though. I dont even see a Karpathy mentioned anywhere in context of this article.
