One of the largest casualties of the internet is the evolution of natural languages and regional dialects has slowed, if not stopped.

What makes you say so? I think internet slang is a vibrant counterexample.
You might have a point with the regional dialects; itβs probably being replaced with the development of jargon within interest-based communities.
Internet slang passes so quickly its hardly ever adopted by the wider community. I think "LOL" is the only one that has really stuck so far, but that's just an acronym.
