Quote from dcraig:
I'll confess up front that I haven't read Kurzweil's book, and nothing I have seen of what he has been reported to have said makes me want to.
The Time piece is basically a load of old nonsense. Conflating computer processing speed with artificial intelligence is just dumb. Just because you can calculate the digits of pi to some remarkable precision ten times faster than you could three years ago does not confer any extra intelligence on the machine.
Most software these days is written in object oriented languages and there is no prospect of that changing anytime soon. But object oriented languages date back at least to SIMULA in the 1960's. If you could transport somebody working with SIMULA in the 60's to the current day, they would have have no trouble in quickly adapting. There is no qualitative leap at all.
In reality progress on AI has been quite slow and some of the early researches would surely be disappointed at the rate of progress. The prospect of an AI that can rival human intelligence in any generalized sense looks as far off as ever. A gazillion iPads being used for self promotion on Facebook are not going to change that situation.
This is not to say that there will not be huge developments in computing and communications but as far as a "singularity" goes - read Arthur C Clarke; far more entertaining.
Kurzweil apparently thinks that climate is not a problem because the world will be powered by solar power by 2030 anyway. There are any number of reasons to dismiss this as a load of old nonsense, but the lack of any economical method of electricity storage (other than pumped hydro which is limited) will remain the killer for the foreseeable future. For example Germany has ~15GWe of PV solar capacity. But in winter, the peak output at the best time of the day on many days could not crack 1GW. You are talking stupendous amounts of storage at even more stupendous cost. In facts months of storage. Blind faith that this can be done, based only on progress in electronics where miniturization is king is just rubbish.
Fantasies wrapped up in some sort of technological cargo cult may be soothing for some, but I prefer a reality based approach.
