You've probably never thought about why we still measure engines in horses. It's 2024, and we're quantifying electric motors using an 18th-century coal miner's approximation of how fast a pony could haul rocks out of a pit.
But here's the thing: horsepower isn't really about horses. It never was. It's about the rate of work. The speed of extraction. And once you understand what James Watt was actually measuring when he invented this unit, you'll see it everywhere in the digital landscape—especially in how platforms measure their ability to mine your attention.
The Physics of Extraction
Horsepower is a unit of power, and power in physics has a precise definition: work divided by time. One horsepower equals 746 watts, or the ability to lift 550 pounds one foot in one second. Watt didn't pull this number from thin air. He watched horses turning capstans at breweries, measured their output, then deliberately lowballed the estimate to ensure his steam engines would always exceed expectations.
The genius wasn't in the measurement itself. It was in creating a standard that made extraction rates comparable. Before horsepower, you couldn't easily compare a water wheel to a windmill to a team of oxen. After horsepower, everything that did work could be quantified on the same scale. You could calculate efficiency. You could optimize.
You could see, with cold numerical clarity, exactly how much value you were extracting per unit of time.
Measuring the Unmeasurable
Now think about engagement metrics. Time on site. Click-through rate. Scroll depth. These aren't just statistics—they're the digital equivalent of horsepower. They measure the rate at which platforms extract attention from your cognitive reserves.
When TikTok's algorithm calculates that it can keep you watching for an average of 52 minutes per session, it's not measuring entertainment. It's measuring extraction rate. The platform has X amount of horsepower: the ability to convert Y amount of your finite attention into Z amount of advertising exposure over time T.
Just like Watt's steam engine, the system is optimized for one thing: increasing the rate of work. Except the coal seam being mined is your consciousness, and the pit never runs dry because your attention regenerates every morning when you wake up.
The Conservation Problem
Here's where the physics gets darker. Power is the rate of energy transfer, and energy is conserved. In a closed system, you can't create it or destroy it—only convert it from one form to another. The chemical energy in coal becomes heat becomes mechanical motion becomes electricity.
But attention isn't conserved. It's depleted.
When you spend an hour watching YouTube shorts, that hour doesn't transform into something else. It doesn't become rest or growth or connection. It just vanishes, converted into advertising impressions and engagement metrics that live on servers you'll never see. The extraction is one-way. The horsepower rating keeps climbing—platforms get better and better at holding your attention—but you never get more efficient at resisting.
In thermodynamics, we call this entropy. The universe tends toward disorder, and every energy conversion loses something to heat. In the attention economy, every scroll loses something to the void.
The Arms Race of Efficiency
Watt's steam engine sparked an arms race. Once you could measure horsepower, everyone wanted more of it. Bigger engines. Better fuel. Tighter tolerances. The Industrial Revolution wasn't just about steam—it was about the relentless optimization of extraction rates.
You're living through the same arms race now, except the engineers aren't optimizing pistons. They're optimizing dopamine delivery. A/B testing notification timing. Training recommendation algorithms on billions of data points. Measuring exactly which shade of red makes you 2.3% more likely to click.
Every platform is in a horsepower war. Instagram needs more than TikTok. YouTube needs more than Instagram. The one with the highest extraction rate wins the most advertising dollars. And you—you're the coal seam. The resource. The thing being converted into value at an ever-increasing rate.
The efficiency gains are staggering. What took a newspaper an entire day to capture—your attention during morning reading—now happens in seconds. Infinite scroll. Autoplay. Push notifications. The horsepower rating of digital platforms makes Watt's steam engine look like a hand crank.
The Measurement That Measures You
Here's what keeps me up at night: Watt's horses didn't know they were being measured. They just pulled. Day after day, turning the capstan, unaware that their labor was being quantified, standardized, and ultimately replaced by something more efficient.
You know you're being measured. You've read the terms of service (or at least skimmed them). You understand, abstractly, that your data is being collected. But you keep scrolling anyway, because the measurement isn't just passive observation—it's active optimization. Every data point makes the system better at extracting from you specifically.
The horsepower rating increases not just for everyone, but for you. Your personal extraction rate, calculated in real-time, optimized by models trained on your behavior. The engine learns. The efficiency climbs.
The Unit We Need
Maybe we need a new unit. Not horsepower, but something that measures the opposite—the rate at which you reclaim your attention. The work you do per unit time to resist the extraction.
Call it resistance. Call it friction. Call it whatever you want. But understand that in the attention economy, the physics is real. Power is being measured. Work is being done. And the rate of extraction keeps accelerating.
James Watt gave us a way to measure how quickly we could tear resources from the earth. We perfected it. Now we're using the same logic to tear something from ourselves.
The horses, at least, got to rest at night.
