The vowel symbols were never truly required for reading, as is the case for most semitic languages. They became common when Hebrew declined as a spoken language to teach people how to properly read the Torah. Since the revitalization of Hebrew as a spoken language this aid is required only for language learners. Also, the language has started to evolve again (that's what invariably happens with native speakers). Slowly of course, but if I may guess, any vowel symbols on existing texts will be of purely historical interest by the end of the century.
