The predicted outcome is probably correct but technology is not its root cause. The primary cause is the animal preference for hierarchical social structures where the top have the largest possible amount of power and control over those at

> the main problems are subthreshold leakage and dynamic power. This is exactly correct. Even at 28nm, many SoCs are intentionally using less than the max manufacturable transistor density, due to dynamic power/thermal constraints.

With 16nm parts in production now, I suspect conventional NAND flash has less an 8X density increase, and less than 10 years left, before we need some totally new tech to keep the party going. AFAICT memristors will not be anywhere near rea

Unfortunately, the claim that "Most mining at the moment is being done at a loss." is unsubstantiated and highly debatable. It's nearly impossible to establish the efficiency and USD-production-cost of mining technology being

However, other passengers on the jet will form little cliques & play Game of Thrones with each other, with the losers getting thrown out of the plane. If you fail to join the right clique, sooner or later, you'll be skydiving. Some

Well, it's a cold, calculated national security decision made by people who are naturally very secretive. They have nothing to gain (in their view), and something to lose, by revealing capabilities beyond those that are already public.

It's quite likely that the people in charge of military surveillance will prefer, and succeed, in getting continuous coverage of the entire Earth. Really want to avoid a "Sorry, Mr. President, we don't have coverage there&quo

My guess is that the US, Russian, and Chinese militaries have the interest, and operational ability, to track every in-flight commercial jet all over the world. The IR signature alone makes a commercial jet obvious at any altitude as long a

Indeed: the writer comes off as a major narcissist, with a minor in status display ("Harvard MBA/VP Wife"). I suppose a near-total lack of empathy for your fellow man is, if not defendable, at least an understandable trait fo

If you use Milton Friedman's (IMO, most-correct) definition of inflation as 'expansion of the currency supply' then Gold has actually tracked USD inflation extremely well, and the rate is far higher than the CPI.

OK, I'll bite. Name 5 products or services that have significantly improved in quality at constant cost, or declined in USD price at constant quality, over the past 10 years (excl. high-volume offshored consumer electronics, which of

Our current global economic system was intentionally designed by (and for) a very small Elite, over roughly 4 centuries. Those at the very top are certainly not typical victims [1] of the system they carefully create; indeed, history shows

While way more than $600,000/day of developer time goes into making thousands of lame, derivative cell phone games that less than 100 people will ever play. Fueled by the mostly-irrational hope of creating That One Big Hit.

Once the cache of pre-charged batteries is empty, the latency is the charge time (~60 mins) and the throughput is the charge time multiplied by the number of chargers they have. So when they run out of pre-charged batteries, have 10 charger

Even ignoring the range differences, this is misleading marketing. What happens when 500 cars show up at an urban Tesla battery swapper within 30 mins of each other on a Saturday morning? Anyone who's been to a Costco gas station knows

TV is fading. Yes, Baby Boomers still watch it. But those under 30 mostly watch video on phones, computers, tablets now.

That is a noble goal, but it's one of hundreds of often-conflicting noble goals. It's not inherently wrong to design a toaster that fails to work as a refrigerator.

Diverging from your main point a bit: 2MH/s is unrealistically low. For a couple thousand dollars you can build FPGA HW that can do several billion SHA1 hashes/s. The bitcoin mining world is getting 400-450 SHA256 MH/s from a $130 chip. Wit

It's not a failure for Facebook obviously. It's a failure for their institutional and retail investors, who were sold a very high initial valuation with little near-term upside.

Space does not have air friction, but it still has gravity, which you still need a large amount of energy to counter, if you want to move a massive object to a specific spot.
