@PlumbNick Similar vibes to Antelope Oregon, 1981-85. Didn't end well.

@ArtemisConsort Also, ethnic group dynamics play a huge role in behavior. Can't test for it.

One American working with Brazilians is not the same as twenty Americans working with Brazilians. Ethnic group dynamics are revealed at a certain ratio.

The “solution” here isn’t really a feature tweak, it’s structural. What Karpathy is describing is the breakdown of the phone network’s trust layer.

Phones were originally built on the assumption that a phone number mapped to a real, accountable entity. That assumption is dead. Caller ID has been hollowed out by VoIP spoofing, cheap number generation, and offshore call farms.

So the fix isn’t another app filter - those will always lag behind. The fix has to be protocol-level authentication:

1. Cryptographic caller verification - Calls/messages should originate from verifiable cryptographic identities, not just 10-digit numbers. Think of it as “email SPF/DKIM/DMARC” but applied to telecom. No cryptographic signature = auto-blocked.

2. Carrier-level enforcement – AT&T/Verizon/etc. already know when a call is being spoofed across their networks. They don’t stop it because spam call volume = revenue. The only way this shifts is regulatory or user-mass pressure that makes spam-blocking a profit center instead of spam itself.

3. Zero-trust phone defaults - The “default allow” model (all numbers can ring you) has to be inverted. Default should be “no one can ring you unless you’ve explicitly trusted them or they’re cryptographically verified.” That means whitelisting + authenticated IDs become the norm.

4. New network layer – Longer-term, voice/SMS has to migrate off the legacy PSTN into IP-secured protocols (like Signal does for text). That’s where authenticity + end-to-end encryption + anti-spam heuristics can actually be embedded structurally.

So the real answer:

The phone system as we know it is obsolete. As email required spam filters + authentication to remain viable, voice/SMS requires cryptographic trust injection. Until then, the only real personal solution is nuclear - whitelist-only comms, everything else default silent.

@christopherrufo Strange, how China also went through a cultural revolution at this time except it was far, far more extreme.

Manufacturing can replace traditional craftsman-made buildings.

Chinese firm Broad Group built a ten-story building in just over 28 hours. The rapid building technology depends on fully-fitted modules. Could the technology solve the Gen Z housing crisis in cities?

There is almost no correlation between the amount a school district spends per student and test scores.

@gossypiboma666 @duns_sc0tus I've also reflected plenty on this and have come to the same conclusion. Forced happenstance interactions plus low friction, low dependency, high proximity relationships make for a tighter community.

@schizoretard18 "The all-wing and jet-propelled aircraft program ended when the second prototype had a fatal crash following two successful test flights. In April 1945 the U.S. military found the V3's unfinished parts ... in different locations in Germany." ~Smithsonian

My priority for my kids is that they learn math, code, design, and above all, to express their own ideas eloquently and fearlessly.

@justicetracking do you know how to find traffic crash investigation reports?

[KVUE News @KVUE]

17 people were involved in the collision, according to ATCEMS. Here's what we know so far: https://t.co/8hPyPp5X7i

Modern western welfare states mean that you can never really go hungry. Even the poor have cars and enormous televisions, but no struggle and few options. It’s a society where people have nothing to fear, and also little to live for.

There is your birthrate crisis. People have fewer kids when they don’t need them for when they’re old and caring for them as children is a burden. It’s a crisis of meaning that won’t be solved with tax credits.

Would be great to spend less time getting to/from the airplane than the flight time itself.

@MyLordBebo Ok, now do Xi.
