Are you serious??? The man casually made an app that allowed millions to customize themselves. When has Bp or Batman consistently made better and better suits still that allowed them to take on threats with physicals much greater than themselves? Justice buster got by on plot, hell bat was made initially with help from the JL and even when he remade it, it couldn’t last long. When have they have been able to make suits to engage cosmic threat, when has their tech been considered advanced years in the future by some of the most advanced minds in marvel like the high evolutionary? When have they made tech for almost any kind of situation? When have they’ve made tech capable of analyzing personal gear of a top smartest mind in the world? (Dr Doom) When have they made something as strong as Sol’s hammer? Lastly, BP has admitted multiple times that Stark is smarter to further stack on to these feats and has needed Wakanda’s brightest minds combined with his own just to keep up
