Definitely better to charge an EV with clean energy. But it’s probably better to charge an EV with dirty electricity than it is to keep using a combustion vehicle.

IIRC a gas vehicle is something like 20% thermally efficient, whereas a coal/oil power plant can be up to 60%. So even if my EV is charging off oil or coal, I’m getting 3x the energy per unit of emissions compared to a gas vehicle (though who knows how that translates to miles of range).

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.

Having express self-checkoit is great. The Kroger near me went full-self-checkout. They have large kiosks that mimmic the traditional checkout belt kiosks, except the customer scans at the head of the belt and the items move into the bagging area.

If you have a full cart, you scan all the items, checkout, walk to the end of the belt, and bag all of your items. Takes twice as long as bagging while a cashier scans (for solo shoppers), and because of the automatic belt the next customer cannot start scanning until you finish bagging, or their items will join the pile of your items.

It effectively destroys all parallelism is the process (bagging while scanning, customers pre-loading their items with a divider while the prior customer is still being serviced), and with zero human operated checkouts running you get no choice

Although this is likely from crawling, which would apply to any federated social media too once it becomes large enough to be on their radar.

Already happened with GitHub Copilot.

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.

I think the idea here is to bake it into construction that would happen anyway. If you just need energy storage, keep using batteries. But if you’re pouring a foundation already, why not also turn that foundation into a battery?

ABSOLUTELY. I just recently capped off the Diff Eq, Signals, and Controls courses for my undergrad, and truly by the end you feel like a fucking wizard. It’s crazy how much problem-solving/system modeling power there is in such a (relatively) simple, easy to apply, and beautifully elegant mathematical tool.
