not just useless - they're profoundly stupid, confusing (weak) correlation for causation, when there's plenty of actual data & insights they could have used instead
I'm not sure anything has epitomized AI for me more than the MLB playoffs commercials featuring completely useless stats. @keithlaw.bsky.social @craigcalcaterra.bsky.social

i’d say the real killer feature of EVs is basically the lack of real maintenance costs.

My social media feeds from today summarized:

1) RFK jr is a horrifying lying sociopath who will kill millions if not stopped.

2) Go birds!

As much as this suggests an option, I’m dubious of the effectiveness.

Malcolm Gladwell has spent well over 10,000 hours being a fucking idiot, that's why he's so good at it.

No one wants to hear this, but it’s true. Either we can value education — not for a select few but for anyone willing to put in the effort — and provide the requisite resources, or we can watch it become a pursuit available only to an elite minority, with everyone else getting a cheap facsimile
There simply is no substitute for the time-, personnel-, & $$$-intensive way of providing quality education. That we don't want to pay for it, as a society, does not make this any less true, & AI cannot fix that. At best, it can poorly substitute for the real solution.

Sure we could reduce the student to teacher ratio, and create an education system that we know works for students. But that would cost money, so bring in the slop.

With Tom Lehrer's passing, I suppose this is a moment to share the story of the prank he played on the National Security Agency, and how it went undiscovered for nearly 60 years.

How long do you think it takes a NYT reporter to order dinner?

Vance combines the wisdom of Dan Quayle, the integrity of Spiro Agnew, the patriotism of Andrew Johnson, and the down home folksiness and charm of Richard Nixon.
We’ve had several kinds of vice presidents — ass kissers and attack dogs, ambitious strivers and marginalized nobodies, blowhards and tryhards — but Vance somehow combines the worst traits of all.

He’s basically Veep Voltron.
