Evergreen tweet: “Everyday I come across more examples of an internet that is increasingly untethered from reality, a hyperreality of interchangeable signs and simulated facts made to fit any world view”
I can literally post this every day it will continue to be applicable

Software engineers are now Claude Code managers. But how can I manage what I’m forgetting how to do myself?

Using AI helps people get higher grades and get their work done faster, but they learn less & suffer on actual exams
I saw this in my own large Intro Psych class:
-the exam average is 85%
-after AI, it shot up to 95%
-after I made the final in person it went to 68%

If I wasn't retired, I'd be going deep on LLMs to avoid getting fired, and remain marketable. However, I wouldn't allow an LLM to do work for me without eventually learning how to do it too. I'd use an LLM as a tool, not a replacement.
I'd also start contributing to an open weight model as a hedge.

this graduation speech moment is notable, and her amazed shock at having failed to read the room feels instructive.

No modern president has glorified violence as much as this one
Here’s Trump threatening violence, calling for his political enemies’ executions, celebrating the deaths of people he didn’t like, and otherwise casually promoting political violence. There was also the small matter of Jan. 6 and subsequent pardons for violent felons.

Oh wow… dry goods, fruits, and vegetables up 49% YoY.
But I thought this was impossible because CPI is only ever 3-5%???
Inflation is an average, there's variance across products, and you don't get signal at the extremes.

If you're going to refuse to use any platform that is using AI for software engineering, you're going to have to stop using the internet pretty soon. This is just the way that development works now, and it's like that because people find it really useful.

This is an incredible photo.
Every photo from Minneapolis looks like this. Cops decked out with guns and full tac gear facing off against people in bathrobes, parkas, and sweatpants armed only with whistles and cell phones.
Yet every verified MAGA chode on X dutifully calls it a riot or violent insurrection.
