A lot of this techno-utopian stuff seems seriously unlikely. Marshall Brain wrote an interesting short story that tries to contrast some worst and best scenarios for technological development. Sadly, I feel the former is far more plausible than the latter. You can read it here: http://marshallbrain.com/manna1.htm
That Manna essay deserves its own post, what a great read.
I just bought a car that knows to stay in its lane and auto-corrects accordingly. It also keeps a determined distance from the car in front of it and will stop immediately if obstructions get in the way. I could conceivably take a 3 hour drive on the highway and never touch a pedal or the wheel. Though, if you don't touch the wheel after a couple of lane autocorrections, it sounds a bell and asks you to put your hands on the wheel.
While I share the overall skeptical attitude, I have to say translation software is already a part of my daily life. I am a bit of an outlier, being a foreign language instructor, but much of these uses are for my personal life in countries where I have a minimal grasp of the language. I frequently have conversations on an app called WeChat which has a built-in translation function. However, the quality of translation software output hasn't noticibly progressed in the last decade or so since Altavista's Babel Fish was replaced by Google Translate. Asian languages are still as likely as not to be rendered into English wordpasta. I'd like to see Kurzweil's past predictions. I always hear techno-utropian say that his predictions have been highly accurate so far (this infographic calims 89%), but I have yet to see the substance. And I'm not about to do the research myself.
