I disagree that all language evolution comes about through laziness. Some people just can't pronounce certain sounds, especially when they are before or after other sounds. This can be caused by dialects, accents, and even physical make-up. When that sort of person either raises children or holds a position of influence, the new "way" of speaking spreads. Anyway, for whomever started this thread - "Really?". The concept there in that statement is essentially asking, "what is the worst that could happen?" Therefore, what scenario is the worst? Worse means anything from slightly less positive than something to horrible, but not necessarily the "worst". In my opinion, language on something like this could potentially evolve due to ignorance of what you are saying, not laziness...
