Maybe he is indicating Irans approach on hypersonic missile technology, because thats the future.
If Iran "is on a fast move, on a highway, regarding missile engineerin" it can be so understood....
Russia is working on them and already succesfully tested, Zyrkon missile
USA also has its Hypersonic projects:
China is working on it
India with help of Russia (Brahmos II) is working on it
so why not Iran?
the question is can iran, ON ITS OWN, without having help from outside or having a copy from this technology, creat a hypersonic missile?
Nearly all Irans missiles had evolution and origin from missiles from other countries (China/Soviet/..)
Can Iran create a hypersonic missile on its own, wothout a copy?
