probably but he wasn't on the same level so there won't be the same expansionNot so sure - Darius I who actually invaded Greece was part of a cadet branch of Cyrus' family. Highly likely that absent Cyrus I that another Persian possibly Arsames (Darius' grandfather and Cyrus I's cousin) would take on the Medes.
Butterflies aren't always strong enough to push the inertia of pre-existing issues down a totally different route.

They wouldn't - but they wouldn't automatically fail to if Cyrus did not exist.Why would Elam-Persia automatically conquer these lands?

Given that they key factor in the the Medes defeat was the defection of their general, it is likely that any competent rival could topple the Medes
Thereafter who knows.
Sometimes the butterfly theory is used to almost justify an odd version of the "Great Man" theory of history. I don't think it follows that if one man is killed that the fall of Median Kingdom and the expansion into the vacuum left by the Assyrians of another polity will not happen because - butterflies.
