Modern Hebrew does have the same vowel diacritics used since the early middle ages, but they're used only in children's books as training wheels, in poetry (e.g. see Haaretz's poetry section: https://www.haaretz.co.il/literature/poetry https://www.haaretz.co.il/literature/poetry), and occasionally to resolve ambiguities in literary prose. They're rarely used in, say, news reports, even to clarify foreign names, which results in common mispronunciations (worse, they even omit the diacritic that distinguishes B/V and P/F, which makes foreign names truly ambiguous -- https://en.wikipedia.org/wiki/Dagesh https://en.wikipedia.org/wiki/Dagesh). BTW, because modern Hebrew was revived from biblical Hebrew, biblical Hebrew is completely understandable to the modern Hebrew speaker, and sounds only a little archaic; something like how 18th century English sounds to a modern English speaker. Shakespeare's 16th century English is more foreign to the modern English speaker than biblical Hebrew is to the modern Hebrew speaker. English has continuously changed, while ancient Hebrew was transported to the late 19th century. Funnily, because the revivers of Hebrew preferred biblical Hebrew over, say, medieval Hebrew, medieval texts might sound more archaic to modern Hebrew speakers than more ancient ones.
