  • Is OpenAI likely to fold?

    They bought in one day a significant % of the worlds memory output for 2026. Two huge deals with two huge companies, announced at the same time. Neither company knew of the other deal. But those deals weren’t even for chips- they were for finished wafers. I doubt very much OpenAI has the facilities to slice and package wafers. So it seems to me the only point of the deal was to kill the DRAM supply market and drive up prices for their competition.

    Wouldn’t be surprised if those finished wafers are going straight in the dumpster.


  • “For this not to be a bubble by definition, it requires that the benefits of this are much more evenly spread,”

    I would correct that to say ‘for this to not be a bubble by definition, it requires that the benefits of this a. Exist and b. Are significant enough to justify the extreme costs of building these systems’

    Right now I don’t see anything coming out of this that justifies even 1/10 of the $trillions being poured into AI.

    In fact I think you could make an argument that the net result is negative, even for businesses that adopt it, due to the increased prices they will pay for hardware over the next few years. If it makes your employees 5% more efficient great, if it makes your technology 50% more expensive in return, not so great.







  • The crazy thing is, none of these articles seem to want to admit that AI is bad.

    As the old quote goes- “A time is coming when men will go mad, and when they see someone who is not mad, they will attack him saying, “You are mad, you are not like us.””

    In such an environment, nobody wants to admit they are not mad, lest they be attacked.

    Or as someone else said- I want a future where machines cook and clean and do menial work, so us humans can focus on art and poetry and writing. Instead we have a world where machines create art and poetry and books, so the humans can focus on cleaning and menial work. I don’t like this timeline.




  • I couldn’t agree more. Acting like a million dollar company is important.

    A million dollar company would recognize that reliable, continuous production and sales is more important to growth than the occasional hickup or a few extra bucks in the payroll budget. Thus, the million dollar company would hire sufficient staff that an occasional absence, even at a critical moment, would not harm production or sales.

    And a million dollar company would recognize that hiring sufficient staff is a wiser and more cost effective strategy than a possible labor lawsuit along with the associated bad PR.







  • Interesting idea. Seriously over-engineered though.

    If you want a ‘human washer’ you don’t need a $350k fancy chair with heart rate monitors. Just take a page out of the automatic car wash.

    Human stands in a stall. Shower allows human washing of hair and face. Then just hold arms out making a diamond in front of you (think TSA body scanner position, but with arms forward instead of upward) and a 360° robotic sprayer starts at the neck and goes down spraying soapy water, then back up again with a slight up angle to get the groin and armpits. Shower comes back on to de-shampoo hair, then the same 360 robot does two passes with clean water to rinse everything off.

    If you get fancy with machine vision and body position sensors, the 360 wand could flip 90° to do the hair and would be angled backward a bit so it doesn’t get water or soap in your face.

    You could build this for a lot less than $350k. And instead of $1500 worth of body sensors you have a $50 waterproof emergency stop button.


  • We used to be. The rules changed about 10 years ago.

    I’d rather have 120v wiring I can do myself than 240v wiring that I have to pay someone $hundreds just to replace a light switch.

    A lot of big appliances require higher power. Dishwashers, clothes dryers, fridges.

    Here in US dishwashers and fridges run on <1500w. A fridge should only use a few hundred watts tops unless it’s horribly inefficient. A dishwasher needs power for the heating element but ours do okay on 1500w, although yours probably heat up faster. We use a different plug for clothes dryers, usually a NEMA 10-30 or NEMA 14-30 (30A at 240v), sometimes NEMA 14-50 (50A at 240v) for really big stuff like EV chargers.
    Our power is split phase (two 120v legs, 180° out of phase, so either phase against neutral/ground is 120v, phase A against phase B is 240v). So with those plugs you either get both legs and ground or both legs plus neutral plus ground.

    Some powers tools, drill press, plainer

    Almost all US power tools run on 120v 15A.
    There’s a few really big ones, mostly designed for professional shops, that need some flavor of 240v, usually with a NEMA 6-15 outlet (like normal US outlet but pins are horizontal rather than vertical). These outlets are uncommon outside of wood shops.

    I never worry about load splitting,.

    The only time I’ve ever even considered this is a. charging my Tesla on 120v, or b. running a space heater and a hair dryer at the same time in the bathroom. :)

    Bottom line- yeah NZ system has higher power density but I don’t think the benefits outweigh the loss of ability to work on it yourself.


  • Okay but that’s more talking about the benefit of a 240v system. The question here was the benefit of the giant UK plug. Personally I would argue that 240v to every receptacle is not a major benefit, because very few devices require 3kw+. And in exchange you get a somewhat more hazardous system.
    I am curious if homeowners in NZ are allowed to work on their own wiring? Here in the US you are…


  • Your understanding is correct. It’s actually a very simple calculation: volts x amps = watts. Watts is the amount of total work done. So to use a water pipe analogy, imagine you have a pressure washer. Volts is the pressure in PSI. Amps in the flow rate in gallons per minute. Watts is how quickly it cleans your sidewalk. Thus, the 500 PSI pressure washer that can put out 2 gallons per minute does about the same amount of cleaning as the 1,000 PSI pressure washer that puts out one gallon per minute. However, as long as the hose can withstand the pressure, pushing out 2 gallons per minute requires a larger diameter hose.

    It’s the same way with wiring. The capacity of a wire is measured in amps. So if a device needs say 1200 watts, feeding it was 240v instead of 120v means you can use thinner wires everywhere. Including in the transformer that powers it.

    However, this type of gain only really makes a big difference when you get into very high power consumption devices. An electric kettle that takes 1500 w, in the US you are almost maxing out a single 15 amp outlet. In the UK the same kettle is using less than half of the outlets capacity. (Of course they just make a kettle that has twice as much output, because the Brits don’t want to wait for their tea). Amusingly, that 3 kilowatt tea kettle is one of the only places where you get a real perceptible advantage from a 240v system.
