Most likely would be Zelenskyy, he supports modernizing government for the Internet Age.
Honorable mention to Pope Francis, who trained as a chemist and has the least political background out of all of them. I bet he would know how to code if he wasn't born in 1936
My dad was born in 33 and was a computer engineer. Started out with assembly and was in high demand due to a lot of old legacy systems. Probably would have learned c# if he wasn't retired by the time it came out. Point is, we can't rule out that the pope knows how to code.
