The land area of the US is about 3.5 million square miles. With a market cap of about $4T, Apple is now valued at more than $1 million per square mile.

Yeah I'm no fan of the gamble-fication of everything either. But I also don't think we're well served by more false conspiracy theories around elections

Worth pointing out that the post you're quoting is very misinformed (polymarket makes money on volume no matter who wins - they have no stake in the outcome):

Roland smiles at the camera in cycling gear, flexing his left. Behind him, a bicycle leans against rocks, and rolling hills extend into the distance under a clear sky.

It's definitely a case of two things can be true. Chatbots are obviously risky for some vulnerable users in a unique new way. But also a lot of the attention is driven by AI haters who just want to ding OpenAI and don't say two words about, e.g. r/Gangstalking continuing to exist in plain view

Bottom line I'd love to ditch the huge power brick my e-bike came with and be able to top up anywhere I can plug in the USB charger I'm probably already carrying, but I'd be scared of breaking/clogging a tiny little C port on my bike.

CHAdeMO tried a couple of years ago, with apparently zero success. But maybe the time is ripe now, piggy backing on the wide availability of USB PD power ICs?

I know we're finally getting away from A/micro B/Lightning hell but it seems like e-bikes are a big enough distinct target that it would be worth standardizing on USB PD electricals over a physically much more robust/durable connector. Could sacrifice high speed SI (480 Mbps should be plenty).

Interesting re the Rivian/ALSO e-bike. Non-proprietary chargers are a huge step forward and USB PD EPR at 240W is plenty for e-bikes. I wonder if there's any chance for a better connector tho.

I'm totally in favor of the ballroom but the White House complex is not the right neighborhood for it. There's not enough parking and I'm concerned about the element it's inviting into the area.

There really isn't much you can do with exaflops of FP8 matrix multipliers other than neural networks, although yes Google search and ads used β€œAI”/TPU even before ChatGPT came out. But still gonna be a ton of stranded Trillium TPU capacity if LLMs don't pan out.
