Is the extrapolation valid? (Score 1)

A driving force in evolution (linguistic and otherwise) is isolation. Population isolation allows for a subgroup to drift from the global average by preventing the dilution of mutated genes (or memes) into the larger population. Historically, much linguistic evolution can be attributed to the isolation of communities from one another, and this evolution has contributed to the regularization of verbs, as well as the introduction of new irregularities borrowed from neighboring languages, etc. But now, with global communication, language standardization, and a much heavier reliance on the written word, might not the ways in which language evolves change? Global communication adds a lot of inertia to a language (although it does increase cross-breeding between languages). I think it is bold (and inaccurate) to extrapolate from past linguistic mutations to the future in the light of the fundamental changes that have occurred in communication.
