My wife: “What happened to our portfolio today?”
Me:
“Reddit is blocking logged out users to prevent AI labs from scraping content for LLM training data.”
The training data:
the AMC employee when you and your buddy ask for the Dune 3 popcorn bucket with 20 pumps of butter and no popcorn
Gen-Z has been calling Diet Coke “fridge cigarettes” and sounds like Coca-Cola’s CEO probably won’t be using that nickname in branding anytime soon
The usefulness of Amazon’s 6-page memo has been nuked by AI-generated text (employees sit in meetings suspecting text is AI and tune out).
Suspicious memos tagged as AI;DR (AI, didn’t read).

dumb starbucks unleashed a creative monster
Tesla VP of Hardware Engineering Lars Moravy explains to Hagerty how the Roadster borrows SpaceX cold gas thrusters to make 0 to 60 possible in 0.55 seconds.
Truly insane:
▫️ 200L carbon-over wrapped pressure vessel
behind seat holds nitrogen at 10,000 PSI
▫️cold gas thrusters push out 80 kN of thrust (equivalent to a single fighter jet engine)
▫️Tesla went with nitrogen because “it just seemed wrong to put fuel into a car” (air is ~80% nitrogen, fair enough)
▫️thrusters same system satellites use to move in space (eg. the “psh psh psh" from Apollo 13 film)
▫️currently takes 6 to 7 hours to refill all nitrogen but Tesla working for it to be 30 minutes
▫️uses leg actuators from Optimus robot to manage downforce on wing

Elon showing Jay Leno the first production unit Tesla Roadster in 2008.
Leno amazed by battery pack with 6,831 lithium-ion cells and gives this take on his first test drive:
“The good thing with electricity is that you get full torque from 0 RPM. In a gas car, you have to bring the revs to 3 or 4 grand and pop the clutch. Most electric cars feel bottom heavy, but not this. It’s eerily quiet. It’s amazing. All you hear is the wind noise. I like that it’s a sports car, not some dorky little 4-door econo-box.”

pump this SI-generated video directly into my veins
The super running shoe arms race is out of control.
Two runners that broke 2-hour marathon mark wore the Adidas Adizero Pro Evo 3. Now, Adidas has made a running shoe with gear shifts…that change the foam from stiff to soft.
Controlled by a runner’s watch for adjustments based on terrain or fatigue. Stiff bounces more for sprints while soft for cruising speeds.

Kylian Mbappé left Nike after ~20 years with the brand and joined On Running.
Mbappé reportedly turned down a 10-year $200m deal from Nike. He’ll get On equity and launch its football category (overseen by Thierry Henry).
He was spotted wearing On’s wild spray-on shoe technology (LightSpray), a process inspired by glue guns that greatly reduces shoe making time with max customization fit potential:
▫️It takes 3 minutes to finish the upper part of the shoe (see video of running shoe sample) vs. 3 hours with stitching
▫️A single person can operate the machine vs. 100 people on a normal shoe assembly line (and only has 7 parts vs. ~150 to 200)
▫️LightSpray using parametric design principles, and computational engineering (instead of traditional pattern makers).
How?
Per NYT, a robot arm sprays “a single semi-translucent synthetic monofilament almost a mile long” on to a shoe mold to finish the upper (which is then “heat-fused to a foam rubber and carbon fibre sole”).
Hellen Obiri won the 2024 Boston Marathon and 2025 New York Marathon while she wore a version of the LightSpray shoes.
Very interested how these shoes perform on soccer pitch.
