Language is an important part of our glorious human civilisation.
Our brains are wired a certain way and the languages we have invented fit with that way. If all people's brains were wired as dyslexics are. How would our languages work?
Our written language of English is inconsistent and not always phonetically spelt. Could dyslexics themselves create their own written language? One which did not have the odd symmetrical some of them suffer with - a set of symbols that uniquely describe all phonetic sounds?
Because if that was possible, with the help of computers it would be a trivial task to convert english into a special phonetic version readable to such people. So the world wide web might become simpler to read.
What of numbers?
The number 19 and 91 might look similar to a dyslexic. But to us, with a brain more appropriately wired. Its obvious that 91 is greater than 19. But by using base 10, we're packing information into just two digits than lower base number systems.
Base 2, binary has the lowest complexity per digit. It might be simpler for dyslexics who have difficulties with numbers to learn about base 2 numbers.
If they can never grasp base 10, then they can always resort to calculator apps to convert from base 10 to base 2 and visa versa.
