Irish, and other minority languages

[Beskar]

We have a Lingua Franca - it's called English, before that it was called Latin. Demanding that everyone have the same first language is like demanding the tide not come in. as soon as you've forcibly purged all the other languages your new super-language will begin to diverge.

Not really. Setting a set standard of practise will keep it mutually the same with minor diverges and evolutions which end up getting incorporated within the dictionaries as the language evolves and adapts. The world at the moment is a heavily chalked up blackboard full of scribbles, what it needs is a good wipe down with new instructions written up, taking the best bits from all the scribbles, forcing a revolutionary change. After that, it is simply done and with how information technology works today it, would keep going for a very long time.

Lots of languages have "hangers on", infact, American English was an attempt to modernise the English language by removing some of them. A fundamental shake-up would force an revolutionary advancement in language (such as a new alphabet, based on the principles I mentioned). Other examples would be the metric system compared to the imperial system. There are ways to make things better, so lets make them better.
