“We have no current plans to make revenue. We have no idea how we may one day generate revenue…once we've built this sort of generally intelligent system, we will ask it to figure out a way to generate an investment return.” - Sam Altman in 2019

I see they are still executing on this plan. 🙃

do-calculus for Humans Is it just a fancy way of saying control for all confounders?

The do-operator is odd, but useful.

Magpies have a reputation for thieving shiny objects, but that’s nothing compared to these kleptoparasite birds in Hawaii, which steal twigs from other nests to build their own:

‘Spot ‘em, scare ‘em’: The nightly battle waged against this Fort Worth critter Every night, residents wage a battle against this smelly, expensive critter in a north Fort Worth suburb.

Wow did this article make me just sick with fury

Fort Worth residents hate nesting neighbor egrets so much they're trying to get Ted Cruz to pass a law removing them from Migratory Bird protections??

Scientists thrilled as an elusive Greenland shark washes up in Ireland | CBC When Dublin scientist Emma Murphy got word that a dead Greenland shark had washed up on the shores of northwestern Ireland, she was gobsmacked. Not only are the massive and ancient ocean dwellers not...

"They are likely far more widespread than we know," [Dean Grubbs] said. "There just aren’t people sampling the depths to frequently see them."

Pinna nobilis - Wikipedia

The sea floor is wild. What do you mean there's a species of clam that can grow up to 4 feet long, has a mutualistic relationship with a shrimp that warms it of predators, and produces a silk-like secretion once used to make paper?

Imagine if in 2028 a Democrat was elected president, and one of the first things they did was go on foxnews and tell them they were being shut down.

I'd probably replay that footage all day on repeat.

Apple taps John Ternus as CEO to replace Tim Cook, who will become chairman Apple said on Monday that John Ternus is succeeding Tim Cook as CEO, with Cook assuming the role of executive chairman on Sept. 1.

Tim Cook is stepping down as CEO of Apple on September 1st. At age 65, this feels like a reasonable time for him to retire from day to day running of Apple.

He’s helped Apple navigate both China and the Trump administration effortlessly so it’s great for the company that he’ll stay on the board.

It's frustrating to receive notice after notice that "We're adding AI into your product, but don't worry! Your privacy is protected. No one is allowed to train on your data." As if training on my data were my one and worst privacy fear. I'm way more concerned about how my data is stored and sold.

Let's imagine you could measure a passive vs active orientation toward technology as a construct *

*ie let's pretend we've done a lot of nice psychometric work to develop some scale that reflects this and we feel good about it and we share a philosophical belief that social science is useful

What are the worst ethical disasters in NLP history?

(I'm teaching "ethics of NLP" tomorrow and history is good for teaching this topic.)

Most are data breaches/releases (AOL search logs, OKCupid profiles, Finnish therapy records...) but what others?

I'll put some other examples in thread --> 1/n

Brain/mind researchers: How do you think about terminology and how it maps to "theories of" {the brain/mind thing you're trying to understand}?

I'm writing & I'm checking in to make sure I capture the full spectrum of ideas out there.

To calibrate, let's consider 3 options.

We have almost no accurate intuition in the physical sciences. We have lots of accurate intuition in the social sciences. Understanding other people is in large part what our brains evolved to do.

Science in the domains of physics, chemistry, and biology is celebrated for producing counterintuitive results that are nonetheless true.

This has misled people about how much evidence you should need before you believe something contrary to your intuition in the social sciences.

This is of particular interest and importance where terminology from the mind and neuro- sciences gets leveraged in AI research. Suddenly, a lot hangs in the balance—not just scientifically but politically, economically—in considering what we mean by “affect” or “comprehension.”

Recently have been putting a lot of thought into what norms govern the movement between folk concepts and scientific concepts. What concepts are resistant to operationalization? Really interesting thread from a cognitive scientist on what concepts we can have “theories of.”

Honesty, ingenuity, precision, and self-dignity are core principles in research from the development of ideas to their implementation. Write your fucking own grant!

A book review cannot replace the book it reviews, but the best ones can offer much the same reading enjoyment.

In a similar vein (but much rarer) are authors’ accounts of the background to their book. Exhibit A: @kph3k’s ‘preview’ of “Original Sin”.

Many profoundly useful inventions rest heavily on information that, until it was applied, was often pretty useless.
Tim Harford considers the usefulness of such useless information:
