I don’t understand this mentality. If we oppose monopolistic sales platforms when it’s Amazon, Google Play, or the Apple store why should we turn a blind eye when suddenly we like a particular company.
I’m not contesting that Steam offers the best user experience by a mile (it truly beats Epic and Gog by miles), but that doesn’t erase the downsides of having a single entity with a grip on the entire market.
The reason the article compares to commercial flights is your everyday reader knows planes’ emissions are large. It’s a reference point so people can weight the ecological tradeoff.
“I can emit this much by either (1) operating the global airline network, or (2) running cloud/LLMs.” It’s a good way to visualize the cost of cloud systems without just citing tons-of-CO2/yr.
Downplaying that by insisting we look at the transportation industry as a whole doesn’t strike you as… a little silly? We know transport is expensive; It is moving tons of mass over hundreds of miles. The fact computer systems even get close is an indication of the sheer scale of energy being poured into them.
The example is pretty standard, but I feel obligated to caution people about the author (just because he’s linked to here and some unassuming people might dive in).
Scott Alexander falls loosely under the TESCREAL umbrella of ideologies. Even in this article, he ends up concluding the only way out is to build a superintelligent AI to govern us… which is like the least productive, if not counterproductive, approach to solving the problem. He’s just another technoptimist shunting problems onto future technologies that may or may not exist.
So, yeah, if anyone decides they want to read more of his stuff, make sure to go in informed / having read critiques of TESCREALism.
Two Vonnegut novels—God Bless you Mr. Rosewater and Player Piano—fundamentally shifted the way I view the world.
The novels primarily discuss the economy, automation, and human wellfare. When I was young I defaulted to a laissez-faire economic mindset, and basically assumed automation and technology would always make our quality of lives improve. I was very much in the Ayn Rand club on economic and moral issues. These books were ultimately what made me reflect and consider the other “spiritual” (in the sense Vonnegut uses the term) aspects of human wellfare. Vonnegut was my introduction to humanist thought, and I owe the vast majority of my personal moral development to the influence of these two books.
Amdahl’s isn’t the only scaling law in the books.
Gustafson’s scaling law looks at how the hypothetical maximum work a computer could perform scales with parallelism—idea being for certain tasks like simulations (or, to your point, even consumer devices to some extent) which can scale to fully utilize, this is a real improvement.
Amdahl’s takes a fixed program, considers what portion is parallelizable, and tells you the speed up from additional parallelism in your hardware.
One tells you how much a processor might do, the only tells you how fast a program might run. Neither is wrong, but both are incomplete picture of the colloquial “performance” of a modern device.
Amdahl’s is the one you find emphasized by a Comp Arch 101 course, because it corrects the intuitive error of assuming you can double the cores and get half the runtime. I only encountered Gustafson’s law in a high performance architecture course, and it really only holds for certain types of workloads.
The script doesn’t go away when you replace a helpdesk operator with ChatGPT. You just get a script-reading interface without empathy and a severally hindered ability to process novel issues outside it’s protocol.
The humans you speak to could do exactly what you’re asking for, if the business did not handcuff them to a script.
