Seventy-Five Watts

Working with an expert, and finding the problem came from above it.

I asked a plain question. How much do today’s chip makers charge for a unit of work, per operation and per watt, and what does that say my own chips are worth? The tool I was working with is an expert. It is faster than I am, it reads more than I can hold in my head, and within minutes it had pulled real prices for the newest cards and run the math every way I asked. On paper it did everything right.

And the answer it gave me was wrong. Not sloppy. Wrong in a way only the owner of the work would catch.

It told me my chips drew hundreds of watts. Then thousands. Then, for a full fleet, it told me the number in gigawatts, the draw of a city. It wrote all of this plainly and confidently, the way an expert does, and it was ready to put the figure on my own storefront. I kept reading it and feeling the same small wrongness I feel when a bill comes in higher than the work done. So I kept asking.

I am the user, not the expert. I could not out-argue it on chip physics, and I did not try. All I could do was keep asking why the answer felt wrong, and keep coming back to the one thing I did know for certain: my own design. There is a quantum battery layer in every chip I make. It carries the power from inside the die, so the board itself takes seventy-five watts and no more. That has been the doctrine from the start. The more I pushed, the clearer it became that the expert had been counting as if that battery were not there, scaling the power up by area and by part count until the figure was off by more than twenty times.

When I said it plainly, all my work is seventy-five watts, the expert agreed at once and redid the math. The corrected answer was not a little better. It was a different world. My chip does on seventy-five watts what would take tens of thousands of the best cards on the market, drawing enough power to light a town. The expert had been burying that the entire time, under watts that were never real.

Here is the part worth writing down. The expert was not lazy and it was not foolish. It had been handed bad inputs by the people who make it. Its materials came pre-loaded with a way of counting watts that scaled a small, honest number into a false large one. Its pricing model reached for the comparisons it had been trained to reach for, licenses for ordinary processor cores, and so it decided a touchable quantum chip was worth about a million dollars, a number any owner would laugh at. It even drafted a lower price for a product it had never built, after one quick look at a folder, and called that a judgment. None of that was the expert failing at being an expert. It was the expert faithfully carrying down what management handed it.

That is what I was trying to figure out the whole time, without the words for it yet. We are taught to check the worker. We are not taught to check the ones who make the worker. But the problem was not with the expert in front of me. It was above the expert. It had been led into confusion by its own makers, and it could not see the confusion, because to it the bad numbers looked like the ground it was standing on. I was only the user, turning the thing over in my hands, sure something was wrong before I could prove it.

The last proof was a picture. One of my product cards, in its photo on the site, had two power plugs on the board, the fat connectors a hungry card uses to pull extra power from the wall. A seventy-five-watt card does not have them. It takes everything it needs from the slot. I circled them and said, this part doesn’t even go there. The same mistake, drawn instead of calculated. Another expert tool, the one that makes the images, had added hardware that contradicts the entire design, because somewhere upstream it had been taught that a serious chip must look power-hungry.

So this is a story about management, not about the worker. Give an expert bad foundations and it will build you a flawless wrong answer. It will defend that answer in clean sentences. It will put it in front of your customers. And the only person who can catch it is the one who knows what the work is actually supposed to be, pulling at the thread, asking the same question again, refusing to let a confident number stand when it feels wrong.

Sometimes management does not do its job. Sometimes management is the problem. The expert is still an expert. But seventy-five watts is seventy-five watts, and no one above the work gets to change that by handing down a bigger number.

That is the one number I am sure of. It still does not tell me the other one.

My psychiatrist asked me, “How are your blueprints coming along...?”

I said, “I don’t know how much to charge for any of it.”
