I do see your point about C++. I was programming when it first came out, back in 1985. However, I've always thought C++ felt "Band-aid-y." It never felt elegant and cohesive to me, the way Objective C does. C++ is like a chainsaw-hang-glider-shotgun-bat; badass, to say the least, but still a clumpy work of bailing wire and duct tape. Typescript feels the same way, only not quite so badass. It's more like the Robin to C++'s Batman.

Having said that, my only exposure to Typescript has been in Angular 2. Having used other tools like Ember, React, and Elm, Angular 2 seems like a magic step backwards to me. I will concede that my opinions on Typescript may be tinted by my experience with Angular 2 though, so I'll give Typescript a stand-alone, honest evaluation, and adjust my opinions as necessary.
