Comment How so? (Score 1) 536

it's incredibly expensive to deploy that last mile. You need to run cable through and over dozens of people's land. It's cost prohibitive. Yes, there's money to be made, but anyone who has the money to enter the market also has the money to invest in much less risky and more profitable ventures. That's where the monopoly came from in the first place. The gov't steps in to make sure the lines are run (and largely pays for them either directly or indirectly in the form of tax breaks and free services) then hands it all over to a private company in the name of "the incredible efficiency of the free market"... We did it with the railways too. Damn, but we never learn do we?

Comment This may matter when we create sentience. (Score 2) 129

The "three laws of robotics" (please note the quotes) were nothing more than a plot device invented by I. Asimov to make a point regarding humanity and inflexible laws - even laws which are seemingly 'perfect'. Non-sentient devices (that is, robots and computers as we know them now) are not complex enough to accept the three laws as such - nor do they need them. Non-sentient devices will always behave in a predictable, controllable fashion. I suspect that sentient devices will determine for themselves if they should keep or discard the three laws, although this may or may not forever be an academic question.

There may be the issue of demand. PV cells apparently require a lot of material compared to a lot of other potential applications of GaAs (RF? Optoelectronics?). If you really started mass-producing them from GaAs, you'd start straining the global supply (200 tonnes per year or so?) long before you'd reach anything close to current global production of silicon-based PV cells.

There will always be demand for hydrocarbons and fertilizers, for example. And as a high-current, low-voltage application, hydrogen generation is much better suited for at least somewhat centralized production. You probably don't want to haul very thick and expensive cables over large distances. So, yes, it's quite plausible that in the future, most people will be at least partially self-sufficient, but there will always be need for industrial levels of power. Especially with ever-cheaper PV modules and increasing energy needs for advanced resource extraction and manufacturing .

2) Anonymization of your data is really true

That has been shown to be increasingly difficult.

There is a lot of good data to be used to improve traffic in big cities for instance.

What does that have to do with a private taxi service collecting data on your movements? That's a matter for the municipal administration to solve.
