Intel makes chips with more than 8 cores.
Granted, it's incredibly expensive (as you point out) and I've only seen them in blade applications. But, they do make them. It's also worth pointing out that on the whole, one intel core gives far superior performance than one AMD core of the same clock speed (see http://www.cpubenchmark.net/high_end_cpus.html). Moreover, Intel's hyperthreading can be of a huge help, if your application profile fits.
Measuring $/core or $/CPU Cycle is not a very accurate way to gauge price/performance.
Sorry, but this is a terrible idea.
Why should something like a strep throat examination cost the same per hour as an MRI or chemotherapy?
All that will do is drastically increase the cost of basic services and make them out of reach of most people, reducing the overall access to basic medical care.
The only statement from the summary I kinda disagree with is the following. "Turns out AMD's Phenom II X4 980, which is over a year old, offers lower frame latencies than the most recent FX processors."
I only mention this because I replaced a Phenom II X4 980 with the FX 8150 last year which increased my average frame rates across the board. Oh well what do I know?
Not like I've experienced the exact opposite of their claims or anything like that.......
It seems that SSD accelerators can be hit/miss. If you take a look at http://www.theregister.co.uk/2012/07/12/velobit_demartek/ for example, some of these products don't seem to do anything - while some seem to actually work.
Like any young industry, it'll probably a while to shake out field until only a few decent contenders remain.
Even if no one uses the same physical media as we do now, and even if no one uses the same file formats, storing an entire PC is likely to solve the problem. You can get a small, inexpensive PC for cheap - a couple hundred dollar atom-based machine should do the trick - and throw a large amount of storage in it. I'm fairly certain that standard power connectors will still be available 30 years from now. VGA connectors may not be, so think about storing a small monitor in there as well (someone else can speak to the chances that a monitor will turn on after 30 years).
Going this route gives you practically unlimited storage for photos, music, text, etc.. with very high chances that it will be recoverable.
