How AI "thinks"

https://youtu.be/rKV5JcALQoQ?is=xuurxSp6FK869raH

Peeking under the hood of AI reasoning, words that the model is "thinking about" but not actually saying are important to achieving results; eliminating the ability to use such intermediate words in the process made some prompts impossible for it to answer. 

When AI was fabricating results, these inner words in the "J-space" indicated the model knew it was fabricating. 

Soldiers use silly string to detect fine-wire booby traps.

Unsinkable metal

Tiny groves on the surface and a hydrophobic coating make these tubes, of 6:33 a very specific diameter, unsinkable. 

Predatory loan takeovers forcing foreclosure

Predatory bankers take over loans that homeowners thought were forgiven, making 30-fold profits and devastating people's personal finances. 

World-record longer drone flight

Is court evidence accurate?

When you actually put court-approved evidence to the test, to scientific method, most methods are woefully inaccurate. 

Modular homes - barriers to adoption

https://youtu.be/2pbYafEcsbk?is=GLZ8aOzsr9Hqte_F

The broken system of "stick-built," on-site construction is favored by regulation, permitting, banks and neighbors. Changing that to the modular-friendly process popular in Sweden and China is going to take a long time. 

21:43 "But if we really could build homes and apartment buildings 20 to 30% cheaper, twice as fast, make them more environmentally friendly, and make them with better materials then maybe, just maybe, one day, we could address this housing shortage"

Horses rebuild after desertification

https://youtu.be/Hl8vErrqjKY?is=nO5pfnHNYYIOS4k_

Start at 9:02. Horses selectively trample bare ground, not the grasses they eat. Seeds in their dung germinate better after traveling through their gut, essentially providing a 11:20 "self-watering, pre-fertilized seed packet." Nitrogen levels rose, insects, then birds, and then predators started to return. 

21:25 China had planted 66 billion trees in a failed attempt to thwart desertification, but 21:58 grasslands require 90% less water than trees. 

By 2023, a desert that was 23:27 expanding by thousands of km² per year was now shrinking by 47 km² per year. 

Homeless

Such a depressing report - hard-working people sleeping in their cars, getting evicted and living in motels, surviving on food stamps. Not addicted, not avoiding hard work, just struggling. 

 Los Angeles has a higher homeless population per capita than Seattle. In the city of Los Angeles, the rate is roughly 1.1%, while Seattle's rate is closer to 0.9% to 1.0%

Recycling aluminum

Gifting to grandkids

https://youtu.be/L_uRTIZKL4Y?is=fWo84cNU_vIoNswM

Gifting to relatives under 19K/yr is ok under IRS rules, but Medicaid counts this as wealth that precludes them from covering nursing care. Instead, 2:42 use 1) a Medicaid asset protection trust, taking the funds out of your name, or 2) a promissory note, lending the person the money with a payback structure. 

Give grandkids money as a structured trust with a distribution staggered between age 25 and 30. 

8:57 Don't put grandkids on the deed while you're alive, but leave the home to them in a 9:20 revocable living trust so they get a "stepped up basis" of the value when you die for capital gains taxes. 

9:46 A trust allows you to decide when they get the money. 

10:48 include a "letter of wishes" with the gift - it's not legally binding, but then their parents can substantiate "that's not what Grandma wanted you to do with that money," which is sometimes just what a 20-year-old needs to hear instead of blowing the money. 

Paying people to be creative: Ireland’s basic income for the arts scheme becomes permanent

Ireland’s basic income for the arts scheme becomes permanent. Interestingly, perhaps to avoid accuse of the system or to provide incentive to produce saleable art, "artists can receive support for three out of every six years."

100-fold difference in monetary effectiveness of charities

GiveWell found four charities that can save a child’s life for about $5,000 in donations.

The four charities that achieve this level of cost-effectiveness do quite different things. One focuses on providing vitamin A supplements to children, the second provides seasonal medicine to protect children from malaria, the third distributes bednets to protect children from malaria, and the fourth incentivizes caregivers to give children their necessary vaccinations.
