In her book Proust and The Squid: The Story and Science of the Reading Brain, Maryanne Wolf writes about the power of an alphabet. In particular she focuses on the ancient Greek alphabet and observes, "Young Greek pupils were given an almost perfect alphabet with almost perfect rules of grapheme-phoneme correspondence. As a result, these pupils could gain fluency in literacy far sooner than their Sumerian, Akkadian, or Egyptian counterparts." (p. 68)
Put another way, there is incredible power in an alphabet, which allows for unending combinations, as opposed to a pictographic language in which whole ideas are represented by images. Even today, you can communicate with greater sophistication, greater depth, and greater novelty with a 26-letter alphabet than you can with a hundred emojis.
The Roman poet Lucretius noted this as well in his work De Rerum Natura, or On the Nature of Things, the first century B.C. didactic poem that explored the world of atoms. In Book 2 we find the following.

significant, eadem fruges arbusta animantis;
si non omnia sunt, at multo maxima pars est
consimilis; verum positura discrepitant res. (DRN 2.1013-1018)
