What's the level of mutual intelligibility/transferrenc between ancient/modern Greek?

[Geticus]

The above post: Ancient Latin was a dialect of ancient Greek.

Linguists: Ancient Latin was one language, Greek another.

Do you really think you speak for all linguists?
Cicero remarked in one of his books about how many Greek words were used in Rome during the early Republic.
Pronunciation habits change through a process called sound change. If you studied Greek and Latin in some depth (I have) then you would notice how many shared radicals exist in both languages. I really don't need your facile cutdowns, either.
