2026-05-05T19:52:01Z

The fact that Google decided to dump a 4 GiB language model file on every Chrome installation is yet another sign of how the generative AI craze is unsustainable. Don't look at it from the side of users, look at it from Google side. Having every user download a 4 GiB monster which will need to be routinely updated is a significant cost. It takes a ton of bandwidth to do that, far more than Chrome updates consume. And yet they're doing it because they're desperate to externalize the cost of "AI".

You should ask yourself, why are the vibe bros obsessed with coding now? Weren't they busy trying to put artists out of work? Writers? Translators? Well, it turns out that in practically every other sector gen AI has basically become a liability. You use it hoping to save time and money, it turns into a PR disaster, you get to redo the work again, you saved nothing, you won't try again. So that's why. They're running out of options to peddle their snake oil.

The tech sector needs to get its act together on software quality and optimization because frankly we suck.

You might also remember that Raptor Lake CPU problems get worse over time. That's because circuits degrade, and applying the wrong voltage can cause them to degrade faster. Circuit degradation is a research field of its own, but its effects are broadly the same: resistance in wires go up, capacity of trench capacitors go down, etc… and the combined effect of these changes is that circuits get slower and need more voltage to operate at the same frequency. 28/31

In Raptor Lake's case a very common pattern that me and others have noticed is that sometimes the wrong 8-bit value is delivered. This happens when reading 8-bit registers such as AH or AL, which are just slices of larger integer registers, and don't have dedicated physical storage. The operation that pulls out the higher or lower 8 bits of the last 16 bits of a regular register is usually done via a multiplexer or MUX. 25/31

_________________________

The speed at which signals propagate in circuits is proportional to how much voltage is being applied. In older CPUs this voltage was fixed, but in modern ones it changes thousands of times per second to save power. Providing just as little voltage needed for a certain clock frequency can dramatically reduce power consumption, but providing too little voltage may cause a signal to arrive late, or the wrong signal to reach the pipeline register, causing in turn a cascade of failures. 24/31

When a clock cycle ends, all the signals resulting from a pipeline stage are stored in a pipeline register. A storage element - invisible to the user - that separates pipeline stages. So if a stage adds two numbers for example, the pipeline register will hold the result of this addition. The next cycle this result will be fed to the circuits that make up the next pipeline stage. If the result of the addition I mentioned is an address for example, then it might be used to access the cache. 23/31

To understand how this works keep this in mind: the maximum frequency at which a CPU can operate is dictated by the longest path through the circuits that make up a pipeline stage. Signals propagating via wires and turning transistors on and off take time, and because modern circuit design is strictly synchronous, all the signals must reach the end of the stage before the end of a clock cycle. 22/31

In the early days of integrated CPUs this state was not only visible to the user, but corresponded physically to what was in the core. The registers corresponded to entries in an actual bank of SRAMs inside the core, the instruction pointer was a physical register that would be read every cycle to fetch instructions from memory. In today's CPUs all these things are merely abstractions and the underlying physical reality is dramatically more complex. 4/31

Let's start with logic bugs. As you probably know a CPU has a certain amount of visible state: a set of registers that contain data and which is manipulated by the instructions, an instruction pointer pointing holding the address of the executing instructions, a set of special registers to alter the core's behavior, for example by changing how floating-point operations round their operands. 3/31

The root of all these issues is fundamentally the same: complexity. Modern cores have become so complex that it's impossible to demonstrate at design time that they will work reliably under all possible conditions, and thoroughly testing them is also infeasible. In addition to ever increasing logic complexity the the conditions in which they operate have also changed: fixed voltages and frequencies are a thing of the past, complicating physical design. 2/31

In the early days of personal computing CPU bugs were so rare as to be newsworthy. The infamous Pentium FDIV bug is remembered by many, and even earlier CPUs had their own issues (the 6502 comes to mind). Nowadays they've become so common that I encounter them routinely while triaging crash reports sent from Firefox users. Given the nature of CPUs you might wonder how these bugs arise, how they manifest and what can and can't be done about them. 🧵 1/31

When talking about DRAM please don't use the term "shortage", call it what it is: price manipulation.

Shortages are when things you want to buy cannot be bought anywhere, but DDR5 memory kits are widely available. There's hundreds of different types in stock at online retailers. I've yet to see a kit that is actually out of stock. This is the tech industry attempt at keeping high margins at a time when computer sales were already predicted to be declining. Don't fall for it. It's a scam.

The price increases on RAM and SSDs are out of this world. Possibly above the 2020 profiteering. Just look at the graph below showing an almost 800% jump that went down to only 400% with the "generous discounts" of this time of year.

There is no way "demand" justifies this. This is vendors agreeing on jacking up the prices because they hoped that AI or Windows 10 planned obsolescence would drive up demand and it didn't. So now they have to find another way to please investors and shareholders.

A few pictures of this machine and a few more ways in which this is better than a consumer one:
* the keyboard is solid and comfortable
* you get a touchpad with 3 separate buttons and a trackpad
* the hinges are sturdy
* it's very easy to open up for servicing
* the cooling system is well done and doesn't blow hot air on the screen
* the bottom case is solid magnesium
* you get USB A & C, HDMI and Ethernet ports, an SD card reader and a headphone jack
* the camera has a lid to block it

A friend needed a new laptop and was about to buy some consumer-grade garbage for ~500-600€. Fortunately he asked me before committing to it, and we found a second-hand AMD-based Thinkpad T14 for 300€. It's stupidly powerful for what he does, has much better connectivity and a much sturdier case. It was in really good condition too.

Long story short, stay away from consumer laptops. There's second-hand business machines that are both better and cheaper.

Counterpoint: there are millions upon millions of old consoles readily available in the second hand market. They come with gigantic catalogs of old games, some of which all-time classics which you can sink hundreds of hours in. The games are also cheap even without considering the modern not-exactly legal clones, and they won't disappear from a "digital" catalog one day.

There is no need to buy a new console. Buy an old one and enjoy your time with it.

One of the side-effects of the AI bubble is that we stopped talking about alternative solutions to computing problems. Everything needs to be solved with "AI" - meaning an LLM - and nobody stops and asks if there is an alternative. This drives me mad because LLMs are not only unreliable, but also shockingly inefficient. And I'm positive that for most tasks there *is* an alternative algorithmic solution that is more reliable and less expensive.

entire data centers are being built using borrowed money. The loans for those data centers are being sold as part of retail financial products with the value of the data center (and the GPUs inside of it) as a collateral. When the bubble bursts those data centers and their contents will be worth very little. That's subprime mortgages but with data centers instead of houses. Given 10s if not 100s of billions are involved it's a massive financial time bomb.
