If you shot all the people you believe are demon possessed, there will be far less people you believe to be demon possessed. That doesn't make demon possession real.

Eugenics is based in part on gross oversimplifications of genetics and in part on the absurd idea that attributes like economic status are biologically heredity.

True, but some of us are willing to accept that the universe doesn't give a fuck about ideology.

When AGW first became a big issue in the 1990s I was talking against it as a big scam on Usenet; particularity my old haunt talk.origins. it was when one of the regulars, a biologist (why any scientist would waste his time debating Creationists I'll never understand), pointed out to me that the theory was reasonably well supported, there were a boatload of papers and that science isn't the product of emotional need, and I finally accepted that AGW, even if it suggested things that I didn't like, was legitimate science.

Apparently the early script drafts had a more plausible explanation: that the spare brain capacity of humans in a dream-like state was used as processing power to run the AIs. One of the editors thought this was too complicated for a movie-going audience to understand and so replaced it with a magic perpetual motion machine.

Translation is like predicting the weather. If you want to do an okay job of predicting the weather, predict either the same as this day last year or the same as yesterday. That will get you something like 60-70% success. Modelling local pressure systems will get you another 5-10% fairly easily. Getting from 80% correct to 90% is insanely hard.

For machine translation, building a database of 3-grams or 4-grams and just doing simple pattern matching (which is what Google Translate does) gets you 70% accuracy quite easily (between romance languages, anyway. It really sucks for Japanese or Russian, for example). Extending the n-gram size; however, quickly hits diminishing returns. Your increases in accuracy depend on a corpus and when you get to the size of n-gram where you're really accurate, you're effectively needing a human to have already translated each sentence.

Machine-aided translation can give huge increases in productivity. Completely computerised translation has already got most of the low-hanging fruit and will have a very difficult job of getting to the level of a moderately competent bilingual human.

The power consumption of the RPi (especially if you're not using the GPU) is tiny in comparison to anything with motors in it. I'd rather trade a slight reduction in battery life for being able to use a rich programming environment than save a few mW and be forced into a constrained microcontroller development environment. It might be different if I were planning on mass producing a few thousand and needed to save costs, but for a hobby project or even a prototype I'd happily overprovision on CPU power.
