there's a time in the place for everything. static/dynamic typing is a trade off between short-term development pace and long term maintenance. strong/weak typing is a trade off between enforcing high-level constraints and, well, i'm not exactly sure, but (void*) is used all the time in baremetal C . ... that said, i've never read an opinion that weak-typing to the extent possible in javascript is a great idea.
void* is used in C to interact with the raw bytes. In some sense, the raw bytes are the only type in C. You can try to maintain a distinction between a struct RECT{int width; int height;} and a struct POINT{int x; int y;}, but it's perhaps more appropriate to think of that as documentation for the programmer than as an actual type system. As long as your code has poorly-behaved neighbors, the types offer no guarantees.
