Rather than whiffing on a joke, I thought I'd use my new twitter power to share the best pieces of advice I've received: - Find someone who believes in you more than you believe in yourself - Accept blame in 1st person, credit in 2nd - Optimize for learning - Say thank you - Eat

all this talk of Claude + Cursor and becoming capable of building anything you put your mind to (no matter your skillset) is warranted if this is the future, i want to live in it

Your midwestern dad would want you to make sure the excitement translates across the *whole* ballot. @arenasummit is doing great work with both GOTV and training staffers. If you want to support: secure.actblue.com/donate/go…

Your contribution is helping Arena recruit and train campaign staff, deploy them to game-changing campaigns, and support both staff and candidates on the path to victory.

I've been trying to think more about the funniest outcome rather just just the most likely, and I'm sorry to say my mind is clearly not creative enough

Impt to recognize this stems from supply/demand pressures. As a country, we’ve cut back on gov funding of universities (esp. post-GFC), which increases pressure for universities to be *businesses*. Of course universities chase potential students- they have to!

Why is trust in US institutions—esp colleges—collapsing? Here’s a theory. The 21st c has became the age of the unfocused institution—the age of mission inflation, goal ambiguity, and complex orgs losing any clear sense of priority, or identity. theatlantic.com/ideas/archiv…

No One Knows What Universities Are For

Bureaucratic bloat has siphoned power away from instructors and researchers.

I sometimes like to think about the small coincidences of the world that aren't actually all that small. Like: 1. We developed the technology to detect damage to the atmosphere around the same time we developed chemicals that damage the atmosphere

What is HAPPENING here? Between 2012 and 2023, it appears that average OECD reading, math and science scores have declined consistently. This is not (just) about pandemic learning loss. It’s not about one US city. It’s not even just the US. This is the entire developed world.

(1/2) All four of these things can be true at once: 1. Hamas is a terrorist organization that committed horrible acts 2. A full siege of Gaza is only justified if you have little regard for civilians and their suffering

3. Jews, Muslims, and Palestinians who feel less safe today have good reason 4. As a non-Israeli Jew, I am (and have long been) deeply uncomfortable with the conflation between Israel and Jews (noting that Israel has perpetuated this on purpose for decades)

I tried and failed to build a basic app using GPT 3 and 3.5 only....but I can do it with GPT 4. Still clunky, but reality being only 6mo behind the hype isn't too bad
