The spelling and grammar of the English should probably change over the years, but not in an instant, and people should certainly not be allowed to spell words however they want. Lots of confusion, there. Rules must be maintained.

Spelling is a complete mess in English, as is grammar. Those are issues that simply do not exist in other languages (or at least, not to such extents). Now that English is a nearly universal language (and not the domain of Brits and Americans only), it will be bastardised, without doubt.

It will be bloody and many people will scream.
