CMV: languages that use a Latin-script alphabet should move towards eliminating accent marks.

My reasoning: I have some level of proficiency in five languages, using three alphabets between them. I have recently gotten more into language learning and am studying four more, all of which use Latin script (the alphabet used by Romance, Germanic, and Celtic languages among others). In doing so and using my phone for learning programs, I have realized just what a pain accent marks are - slowing everything down and not adding much to comprehension. Words are faster to type without accent marks, and text looks neater. To a fluent speaker, their exclusion should present no impediment to comprehension. 

The concerns: I am aware that there may be a few Latin script languages (Vietnamese comes to mind) that are so reliant on accent marks that losing them would seriously impede communication. These may be excluded. Further, I am aware that demo in accent marks makes pronunciation more ambiguous and may make the language more difficult for children or new learners.  I have a proposed solution: Hebrew normally excludes vowels (a more important textual feature than accent marks) from professional/adult writing, including them only for children or new learners. There might therefore be, say, learners' French which includes ç,é,è,ï,ô, etc and professional French which excludes them.

I would counter that accent marks actually provide for less ambiguity, more possible phonemes, stress marking and ease in differentiation of homophones, while at the same time aiding the reader in inferring the correct pronunciation or meaning.

Accent marks have a wide variety of uses that are ultimately beneficial. In many languages with more-or-less regular rules on stress placement, such as Spanish, accent marks can differentiate words, such as "esta" (this) vs "está" (he is); the former has stress placed on the first syllable, whereas the latter has it on the second. In Spanish, stress usually falls on the penultimate syllable when the word ends in a vowel, n or s, and on the last syllable otherwise. "Está" violates this and needs to be marked accordingly. Similarly, accents also allow for differentiation of interrogative and relative pronouns, cf. "¿quién?" (who?) vs "quien" (who). In other instances, they simply aid comprehension in terms homophones, such as "si" (if) and "sí" (yes). Even more, an accent mark can hold stress on a specific syllable for inflection purposes: the addition of "me" to "mira" in order to form a command would push stress one syllable over, but by writing "mírame," we're able to preserve the proper stress without ambiguity.

In other languages, accent marks change the pronunciation of a vowel without resorting to using additional letters that complicate things. In French, the circumflex opens the vowel so that "hôpital" differentiates from "bonne." The "ô" signifies /o/, where as "o" in this case is "/ɔ̜/" in IPA terms.

We can also look at accent marks as providing an avenue for more vowel pronunciations without the need to either guess or come up with convoluted spellings to achieve them. English has roughly 12 vowels depending on the dialect spoken with an additional eight diphthongs, but there are only five vowels and no accentuation possibilities. In comparison, Portuguese has around 16 vowels, but is much easier to deduce due to five of them being marked nasals with a tilde and the use of the acute accent and circumflex for specific sounds. Even more, Portuguese has a huge volume of diphthongs and triphthongs, but comprehension is easier since accented vowels provide clues on how to differentiate them.
