Fact-check: true. One of my closest childhood friends in Poland has an air-conditioning business (for commercial spaces), but he wouldn't put this devil's spawn in his own house.

@jonathantan1425 Every central European over 40 understands that air which is caused to move by an electric machine is infected with invisible electro-particles which change the polarity of your internal organs, causing all manner of problems.

Is one greater than zero? No, it is just an unsavory compromise with an ugly legacy of colonialism that keeps you from getting to two. (Before you ask: yes, I've just visited bluesky).

Start with a reasonable point - GDP is not a measure of consumer+producer surplus - finish with a silly Soviet-style conclusion.

As measured by GDP, AI will be super undervalued. How would the datacenter of geniuses show up in GDP? . GDP would show raw inputs (aka chip & energy), and raw outputs (aka cost of tokens). But wouldn't clearly reflect the value of the crazy new shit that's being cooked up in

Because of the way that maps are normally drawn, I had never realised that the US (Alaska) and Russia are almost touching. I am shook.

Also, put aside no inflation or interest rate adjustment that further make "indefinite" claims weak.

NYT is making some wild inferences. $5B of accumulated tax losses are supposed to shield profits forever for a $350B company (put aside 80% limitation and future policy changes)?

Estimates are "riddled with errors"? This guy will change statistics. If we didn't know it already who they are, it could have been useful to have these people announce publicly how stupid they are.

The Bureau of Labor Statistics' initial jobs reports are riddled with errors, and the issue is only getting worse. This chart from Issues and Insights sums it up perfectly. @realEJAntoni is ready to bring the accuracy and honesty America needs in its jobs numbers.

NEWS: Trump's administration is discussing buying a stake in Intel Corp. after Trump's meeting with the CEO this week, per sources. It would be a signal of support for the tech firm and its massive, but beleaguered, Ohio chip manufacturing project.

"I ran this by every empirical GDP expert I know" - in this case, a clever way that allows him to say anything he wants without technically lying.

@smilerz91 @brownstoneinst It's interesting because I ran this by every empirical GDP expert I know and everyone said: yes, this is obviously the case but nothing to be done about it.
