Some of the current initiatives will, hopefully, make appropriate and relevant briefing information more accessible and usable - provided that the people defining the future methods are suitably qualified in both aviation and information management matters. However, one of the main reasons that codes remain the most sensible way of disseminating such information for the time being is that it can be read by people without concern about the extent of their language skills in whatever tongue one might choose to use for explicit reports.
There appears to be an implicit assumption in this thread that plain language reports will be in English. It seems easy to forget, or to criticise those whose first language is not English, that working in English is not easy for many people, especially when not using standard phraseology or other standard terms. Remember also that even for native English speakers, plain language English is ripe for misinterpretation. Use of codes can overcome many of the problems that differing languages creates.
We anglophones should consider ourselves very lucky that aviation was established in an era and environment in which English was the naturally obvious language to be used. Aviation is now a truly global industry - consider for a moment if the language to be used for communication was to be based on the numbers of people speaking each language. A quick Google (so absolute accuracy not guaranteed) suggests that the number of native English speakers is dwarfed by both Chinese/Mandarin and Spanish speakers (and by some sources Hindi also comes above English) - to put it into context, one source indicates that a little under 5% of the world population speaks English while Chinese/Mandarin and Spanish are each spoken by a greater proportion of the population and together represent around 20% of the world population. Maybe we could imagine for a moment how we would feel if Chinese were selected for plain language communication in the industry - using codes might suddenly become far more appealing.
With luck, in the future we will all benefit from the pervasiveness of modern IT systems which will enable us to access information in a form or language that suits each of us. Until then, codes work.
