The Undoing Project by Michael Lewis 📚
This was the most influential book of my last year.
What Happens in the Brain While Daydreaming?
The researchers tracked the activity of neurons in the visual cortex of the brains of mice while the animals remained in a quiet waking state. They found that occasionally these neurons fired in a pattern similar to one that occurred when a mouse looked at an actual image, suggesting that the mouse was thinking — or daydreaming — about the image. Moreover, the patterns of activity during a mouse’s first few daydreams of the day predicted how the brain’s response to the image would change over time.
Another downside to having phones (or screens of any kind) always on us is that we’ll no longer daydream.
I wonder if this is why I love the mountains and my cross-country drives: I can’t reach for my phone and thus my mind wanders.
Headed Into the Abyss by Brian T. Watson 📚
I just finished, laying here in my bed, the dogs and cat asleep beside me. Crickets chirp out my window. In the distance a train’s whistle breaks and rolls over the valley.
More than anything, I prize seeing things clearly. Nothing fills me with that particular and precious joie de vivre — that electric sizzle — quite like close proximity to the truth. But most people don’t like the truth. We’ll do anything to avoid it, if we know it at all. So it’s a rare thrill to read something so transgressive in its honesty, so clear-eyed.
Credit to Brian T. Watson for his courage to accept the inevitable, and then to write it. May his acceptance be an inspiration.
AI plus MRI yields the ability to recognize what the mind is hearing.
Today, researchers announced a new bit of mind reading that’s impressive in its scope. By combining fMRI brain imaging with a system that’s somewhat like the predictive text of cell phones, they’ve worked out the gist of the sentences a person is hearing in near real time. While the system doesn’t get the exact words right and makes a fair number of mistakes, it’s also flexible enough that it can reconstruct an imaginary monologue that goes on entirely within someone’s head.
The hardest part of the AI revolution will be the discovery of empirical evidence that free will is a myth.
