"the same mistake the anti-eugenics movement made in 1925 with the Scopes Monkey Trial [wikipedia.org], which fought the teaching of evolution in schools"

All the history of the Butler act I ever read mention they simply feared teaching of evolution would weaken faith, and that they refused our descendance from great apes, as it would shows us as descending from lower beings like animals. At no point the proponent of Butler's act mentioned eugenism, that sound like a modern rewriting of the history. In fact the prominent web sites which promote this thesis are : answeringenesis and creation.com. Fancy that.

With medical devices efficacy and safety are very closely linked. If you're providing a product that monitors blood glucose and you do a poor job of it, your customer makes incorrect medical decisions that are potentially life threatening. The closer an app gets to providing such "actionable" information, the more likely it is that it requires FDA approval.

That said, this "can't be overseen" thing is silly. The FDA doesn't have the resources to oversee ALL smartphone health apps, they don't want to, and they shouldn't. There's no debate there. If the next generation of phones include electrocardiogram electrodes or a sophisticated spectrometer, the FDA is going to regulate the health software using those tools. That's really the news coming out of that FDA statement.

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.

Where can I buy the book ? I am travelling soon and need some SF reading.

Seriously before pretending that in 30 years we will be overwhelmed by cyborg, or whatever new species, we might require , I dunno, EVIDENCE; that such specie is possible or would even react like that. For pity's sake we aren't even progressing that quick with self driving car, people are warry to hell of it, and we are speaking of making a different specie in the same timeframe people think self driving car will come up ? Get real.

That would be great if the government paid for treatment for alcoholics, counseling for family wrecked by alcohol use, covered medical expenses for people who drink, cover damages by drink drivers, paid for medical expenses by people hurt by someone who was drunk, etc

That's a non-sequitur. The cost is born by society. Government is the name of the body that we elect to represent society. If taxing an activity reduces it, which, in turn, reduces a cost that is born by society, then the government has done its job. The point of such taxation is to reintroduce externalities into the costs, so that the market will correctly adjust.

There was a cartoon in a paper many years ago where a collection of self driving cars were assembled into a 'train'. The Doh moment made me laugh.

The advantage of the cars in this model is that they speed up unloading. Go and watch a freight train being unloaded some time, it's a massive endeavour. Now imagine if each of the trucks could just drive off along the roads on its own as soon as the train arrived at its destination.

Because, in the USA especially, lots of Federal government money has been spent connecting the major population centres with roads. Very little has been spent on the rail infrastructure. If you can make it work on roads, then you can take advantage of all of the existing infrastructure cheaply.

Lidar is typically used in situations where you have this kind of interference, but the solution is conceptually pretty simple. You tune the detectors to a specific wavelength and you vary that wavelength between devices. You can typically vary the wavelength in software, so if you detect a lot of interference then you just hop to another frequency. If someone is intentionally blanketing your entire band, then it's not really any different from someone shining a floodlight in the eyes of human drivers - you just point them out to the police.
