The usual reward for a job well-done is a harder job. Your goal is to ensure that is accompanied by appropriate positive consequences as well.

Writing in 1979, science fiction author Gordon R. Dickson looked ahead to 2050 to describe the evolution of the programmable calculator into a general purpose tool that was the size of a typical handheld device. It was a powerful general purpose computer that had a built-in AI (Siri/Alexa) assistant, was integrated into the global data/communication network, supported voice and keyboard input, and had all of the PDA tools such as calendars and to-do lists. The only thing he missed was a touch screen; his device had a keyboard-screen configuration. He saw it as a computer-cum-phone rather than a phone-cum-computer, which is a trivial difference. calc.fjk.ch/library/thank_yo…

Seriously, how is this not malpractice / fraud? When this blows up people who made graphics like this should be sued into penury.
Totally accurate risk assessment…😅

As a general rule, whenever your intuition conflicts with that of an economist, bet on your intuition. Economists are reverse indicators: they are ~always wrong.

I think one of the most interesting moments of the podcast with @johnfetterman was when we were talking about immigration. I think everyone should understand exactly what is happening.

As much as you can personally, intellectually, & morally dislike Trump, a news outlet that promotes a given candidate over another becomes automatically PROPAGANDA.
Half of Donald Trump's former cabinet members have refused to endorse him. The most senior Republican senator calls him “despicable”. Both his former chief-of-staff and former head of the joint chiefs call him a fascist. We are endorsing Kamala Harris econ.st/4ef9Abf 👇

Europe has fallen. Orwell‘s satirical Ministry of Truth is now a dystopian reality. Technocratic totalitarianism has turned lies into truth,and war into peace. Coming to America soon if this election goes to the party of censorship and anti democracy lawfare.
