A stunning size comparison between the Falcon 9 titanium grid fin (1.6m × 1.2m) and the massive Starship V3 stainless steel grid fin (3.8m × 3.5m).

NEW VIDEO!!! The genius reason why @SpaceX only uses 3 Grid Fins on V3 Super Heavy, and why they're asymmetrical. Hope you learn a lot about Grid Fins and appreciate the design decisions! - piped.video/suZNTDISXKw

Incentives explain outcomes
2017: Austin spent $35 million on homelessness. 2,036 homeless counted.
2025: $118 million. 3,238 homeless.
Spending more than tripled and homelessness went up 59%.
If you service the homeless lifestyle, you will get more of it.
The NGOs that run this system get paid by the problem of homelessness, so they have no reason to end it -- in fact, their only incentive is to make sure the problem grows.

The NGOs end up increasing the number of homeless people they manage, because that’s the only way to increase their revenue! Incentives drive outcomes.
“Homeless” is a propaganda word used to describe people on the street who are mentally ill or severely addicted to drugs. The word implies that this is someone who fell a little behind on their mortgage payment and they’re one job offer away from getting back on their feet, which is obviously false if you’ve ever tried talking to a “homeless” person in SF, LA, NY, Austin or anywhere else.
The honest reality is that we need to bring back asylums for extreme mental illness or drug addiction for those who are a serious danger to themselves or others.
Incentives determine outcomes
If you give an NGO a certain number of dollars per homeless person, they will never solve homelessness
SF spends more than $1b/yr (up 5x) and the homeless population has only grown
NGO fraud is so insane, man.

Elon Musk says SpaceX may be able to reduce Super Heavy’s grid fins from three to just two, relying on S-turns for third-axis control during reentry and landing.
