I ride Waymos fairly regularly in Austin. I'm a big fan of Waymo. I think everyone should listen to the @chrislhayes.bsky.social + @binarybits.bsky.social conversation about them.

No, the real inflation rate isn’t 15 percent Jordan Peterson and Jack Dorsey are touting a bogus theory about the inflation rate.

I'm a fan of this @binarybits.bsky.social piece that points out the incredibly simple and dumb error made by shadowstats. There's definitely some wiggle room for how you calculate inflation but you can't be significantly biased in the long term without it being obvious.

Fantastic @binarybits.bsky.social writeup of the Alsup ruling in Anthropic’s case open.substack.com/pub/understa...

But aside from AI training, yet another reminder of the power of analog media. This excerpt is tragic: Alsup’s right about books. But this is exactly how the digital economy works.

On the flip side, progressive cities like Washington DC have put in a ton of traffic calming measures over the last 10 or 20 years.

Apropos of nothing I feel like one of the most important things to help your kids develop is an ability to self-regulate.

There are a ton of people on the internet who don’t understand the difference between describing something and defending it. They think that if you write something about Trump and don’t explicitly add “and that’s bad” every few sentences you are a Trump apologist. These people are morons.

People are betting that FSD and maybe Optimus will give Tesla a far more valuable business than a conventional car company. If that proves wrong (and it probably will imo) the price will crash.

That tilda is important! I don’t believe “fully automating” is a coherent concept. There are only degrees of automation.

I feel like this has been happening for several years now? A lot of ai training data is generated by LLMs now.
