  • Once you have a microcontroller running things, adding new features is just a matter of software. Doesn’t add to the BOM, doesn’t complication production in any way. There’s almost no marginal cost to techify everything, and the people who don’t want those features can just not use them. The small minority of people who want a repairable car that they can understand and maintain in their own garage are undesirable customers who reduce after-market revenue.




  • I don’t so much care where it’s made. The real selling point, to me, for Pi is that their products are well documented, in English, and solutions for problems are easily googled. There’s tons of SBCs out there, some of them even inexpensive, but I can’t tell if any are going to last longer than a single production run. Meanwhile, I can still buy a Pi 3 after almost a decade. Or I can take the hat I made for a Pi3, plug it straight into a new Pi Zero, and expect it to work without changes.

    IPO is a big step down the path to enshittification, especially when there’s no clear, dominant alternative.


  • Even if you ignore all the neuromodulatory chemistry, much of the interesting processing happens at sub-threshold depolarizations, depending on millisecond-scale coincidence detection from synapses distributed through an enormous, and slow-conducting dendritic network. The simple electrical signal transmission model, where an input neuron causes reliable spiking in an output neuron, comes from skeletal muscle, which served as the model for synaptic transmission for decades, just because it was a lot easier to study than actual inter-neural synapses.

    But even that doesn’t matter if we can’t map the inter-neuronal connections, and so far that’s only been done for the 300 neurons of the c elegans ganglia (i.e., not even a ‘real’ brain), after a decade of work. Nowhere close to mapping the neuroscientists’ favorite model, aplysia, which only has 20,000 neurons. Maybe statistics will wash out some of those details by the time you get to humans 10^11 neuron systems, but considering how badly current network models are for predicting even simple behaviors, I’m going to say more details matter than we will discover any time soon.


  • I would rather spend (modestly) more time checking my own than less time standing idly with nothing to do but watch some kid checking out my goods. It feels better to be an active participant. Where it breaks down for me and my 12 items is when all the self-check lanes are clogged with people trying to ring up a full cart of groceries, who still haven’t figured out how to work self-checks, who are encumbered by a baby in one arm and a phone in the other hand, or who just can’t move all that well.

    Managers using the presence of self-check as an excuse to understaff the actual checkouts makes all of those problems worse, and makes the checkout process suck for everyone.



  • Some of that turn is physical plant. Kitchens, especially, are built to serve human forms, where tech solutions to food prep would rather be stand-alone boxes. It’s a far harder problem to make a robot that uses a restaurant’s existing grills, ovens, and deep fryers than it is to make a box that turns out perfect french fries. It’s a riskier proposal for a restaurant to replace its fry station, where a human can make fries, onion rings, egg rolls, or whatever new fad hits tiktok, with a fries-and-rings-only box with less than 10 years commercial proof. Generative AI, for all its faults, is just code that runs on a computer you already have, or maybe in a cloud service with zero physical footprint. Relative to replacing your barista with a vending machine, trying ChatGPT for a quarter or two is practically zero risk.




  • The first kind of bankruptcy, Elon & his Saudi bros keep the company, and the banks lose like 50-90% of their loans.

    The second kind of bankruptcy, the banks get all the servers and office chairs and sell them to either a new data-mining company or a recycler. This isn’t very likely, because most of the value of Xitter is all the people who keep visiting, regardless of whether Elon knows how to monetize them.
