  1. For reliability reasons, the power supply should be significantly derated anyway. The manufacturers have gotten really good at designing them so that they fail just out of warranty because the aluminum electrolytic capacitors wear out.

    The real issue I see is rewritable memory technology.

    Core memory would be out without some way to build sense amplifiers. Latching relays could be used for RAM. Paper tape could be used for mass storage.

    I don't know about the prospects for the Internet. Mechanical computers and later electro-mechanical computers are likely as far as anyone would have got. Its really the transistor that gives you computation that is fast enough to run complex packet switch protocols and gives you signaling properties that are conducive to long ranger "high speed" communications.

    The speed is not so much a problem as the integration and reliability.

    The Analytical Engine could have replaced literal calculators, people doing rote calculations usually for military applications up to World War 2. It would have been too large and unreliable to replace mechanical analog computers used in things like fire control.

  4. CPU power dissipation is limited by semiconductor die size unless junction temperature is increased which lowers operating life and reliability. Since about the start of the Core2 series, CPU die sizes are dropped so power has had to drop as well. GPU makers use a different trade off sacrificing operating life and reliability for performance so while they do use larger semiconductor die sizes, they use even higher power levels. In this respect AMD and nVidia have been in a race to the bottom with nVidia leading.

    One of the first things I look for in a GPU is low operating temperature because I got tired of GPUs failing at about 2 years.

    I suspect what is going to happen is that the PC market will become more like the market existed before PCs. We had "development systems" running operating systems like CP/M which some people were using as PCs. The problem for AMD is that there is not enough demand in such a market to support both them and Intel. Intel talks about moving more into the server business but I do not think that can save AMD when the cost of Intel's CPU development covers their PC processors also.

    And of course all it takes is for MIcrosoft to screw up their PC operating system which they are in the process of doing. With the exception of OSx, the alternatives run just as well on ARM.

    It's good for keeping production volume up as the smaller player but it's not good business.

    Without their own fabs, production volume is something AMD can no longer take advantage of.

    The process also creates greater demand for law enforcement and the courts. Why would they care if the number of criminals rises?

    if you want everyone to switch to renewable energy, it's not a complex process. all you have to do is slowly increase a tax on fossil fuel energy sources (and imported electricity) and use that money to subsidize investments in renewable energy.

    Um, what is in it for the rent seekers and politicians if a Pigovian tax is used?

    The method must be obfuscated for maximum kickbacks and graft. Think of Congress and the Space Shuttle.

  17. I always got a kick out of the instructions on carburetor rebuild kits which warn not to clean parts in gasoline because it is flammable. Not only would we start with the fuel in the fuel bowl which would get thrown out anyway, but what else did they think we would use? Acetone, lacquer thinner, and most of the more effective solvents are just as flammable if not more.
