“Friends, Romans, countrymen, lend me your ears. We come to bury Caesar, not to fucking praise him.” Alternatively, same monologue: “The good men do oft lies interred with their bones, so let it be with fucking Caesar.”

There’s a bunch of Bobo hate in my posting history, and I would just like to say that those posts don’t reflect the person I am now.

I would just like to highlight some personal growth and my ability to change my opinion on things. I would also like to apologize to Mike Bobo, because I never realized all he was missing was a mustache.

I’ll second the Ioniq series being good, and by extension the Kia/Genesis EVs. The whole eGMP platform is solid.

Delightful things happening on Nextdoor.
Food for thought… 
Copied
I keep hearing people complain that gasoline is over $5.00/gal.
And yes, I'd love to see it at $2.00 again. But before we declare gasoline the most outrageously expensive liquid on Earth, let's put things in perspective.
For $5.00, I get a GALLON of gasoline. I pour it into a 4,000lb machine, turn a key, and that gallon will haul me, the groceries, the golf clubs and half the junk in my trunk almost 16 miles down the highway in my pickup truck. 
That's actually a pretty impressive day's work for $5.00.
Now let's compare.
A restaurant sells me a 5-ounce glass of wine for $9. That's about $230 a gallon. And how far does it transport me?
Usually from the dinner table to the men's room.
A fancy coffee shop can charge $6 for a 16oz latte. That's $48/gal. It doesn't transport me 30 miles. It transports me from "Leave me alone" to "Okay, now you may speak."
Bottled water at a convenience store might be $2.50 for 20 oz. That's $16/gal, for something that occasionally falls out of the sky FOR FREE.
A 12oz energy drink at $3.50 works out to more than $37/gal. Apparently caffeine becomes a precious mineral once you put lightning bolts on the can.
Buy one of those little 2oz bottles of "energy shot" for $3. That's $192/gal. At that price, it shouldn't give me energy. It should mow my lawn.
Maple syrup at $8 for a 12oz bottle? About $85/gal. And its principal technological achievement is making pancakes sticky.Vanilla extract at $6 for two ounces? That's $384/gal. For $384, I expect the vanilla bean to come to my house and bake the cookies.
Printer ink can cost thousands of dollars per gallon. And unlike gasoline, it sometimes refuses to come out because the printer has decided cyan is low.
Even that $9 glass of wine deserves another look. At roughly $230/gal, filling a typical 15 gal gas tank with restaurant wine would cost about $3,450.
Of course, after drinking 15 gallons of wine, transportation would no longer be your biggest concern.
So yes, $5.00 gasoline is expensive.
But it's also a remarkable bargain when you think about what you're buying. You're purchasing enough concentrated energy to push several thousand pounds of steel, glass, groceries and humanity nearly 16 miles.
Meanwhile, we'll cheerfully pay $6 for coffee, $9 for wine and $3 for water, then stand at the gas pump staring at the numbers like we're watching the national debt clock.
Maybe gasoline doesn't need better pricing.
Maybe it just needs a fancier name.
"Handcrafted Premium Petroleum, locally pumped, small-batch refined, with subtle notes of octane and dinosaur."
Put it in a 12oz artisan bottle and charge $14.
We'll line up around the block.

I mean, *roughly* each turn is a cache write, the idea being the providers only want to do inference on new tokens instead of the entire stream, most of which they’ve already done inference on. So they cache the existing inference. This is massively simplified.

i mean, just look at how the populists talked about the railroad barons and others like them. "The fruits of the toil of millions are boldly stolen to build up colossal fortunes, unprecedented in the history of the world, while their possessors despise the republic and endanger liberty."

Also worth remembering that people are responsible for running these AI systems. They choose how to train them, how to run them, how to let them interact with their environments, how to use their outputs. Claims by AI companies that "AI will kill us all" are passive voice on steroids.

Slow down frontier model development. Bring open weights to current frontier. Build out local inference providers, stabilize hardware prices, focus on cost and token throughput for a bit. Get our software updated to handle what's being thrown at us. I would not mind spending a beat on distribution.

Independent of policy debates about existential risk, it is worth noting that even if AI development stopped today with the models we have right now, we would still have at least a decade of roiling change throughout much of work, education, and social life as harnesses improve & AI diffuses further

Hi, I didn't wanna make this video but I need to come clean about something. This whole time I've been a p-zombie with no phenomenal experience or interiority. I've been getting messages asking whether there's anything it's like to be me, and the answer is no. I'd say I'm sorry, but, well, you know.
