I think Angilion summed it up perfectly for me with "I'm sceptical but interested".
My view is that it's coming, and I'm very interested indeed when it does. I'll go so far as to say I'll be an early adopter, but only when it works well. I mean, works well enough to be reliable as a business tool, and for multiple languages. French alone doesn't interest me, as I'm fluent enough to get get by. Italian, too. But add Chinese, even Japanese? Then, sign me up.
I'm very sceptical that we're anywhere nead that yet. My guess would be it's some years off.
