I don't actually hate Musk. Although he has done bad, I think he has done far more good than bad. He has, for one, directly improved my quality of life on the transportation front.

You can synthetic short if you have options level 4

Rule changes like this create market inefficiencies that can be exploited by retail; if everything plays by constant rules, the vast majority of alpha gets concentrated in the institutions.

I love shaking up the firms. Gives normal people a chance to build wealth.

On the other hand, reducing supplementation solved my sleep issues. I was taking Magnesium at night, and D+C+Fish+CoQ10+Iron+B12 in the morning.

I don't know what the hell I was taking too much of, but I didn't have a good way to test it. I wish the body had some indicators.

You won't be able to see a doctor when you're sick.

You won't be able to open a bank account to receive your salary.

You won't be able to buy train or plane tickets.

My point is I am most worried that these kind of "digital verification" type things most impact actual necessities. The social media I couldn't care less about. "I just won't use it" isn't really a solution.

Probably in the future nobody will be able to figure out how these things are written, because studying math doesn't make as much money as vibe coding.

I see your concern. The mirrors could be deliberately manufactured to have enough imperfections, or slight reverse curvature, to prevent this. It's possible with properly-designed optics to prevent the mirror from being able to focus on a spot smaller than, say, 1/50000 the mirror's area on the Earth's surface. Make each single mirror only optically capable of focusing down to a 3-mile diameter at best. Then it would be optically impossible to focus all the mirrors to a single 60ft spot, and the theoretical highest brightness at any point on Earth would just be regular daytime levels of light.

I don't think 50000 60-ft mirrors at the height they intend to fly would cause that to happen. Not enough light gathering power.

50000 60-ft mirrors is about the same area as a single mirror 2.5 miles across. So the area of the mirrors is about the area of a city. You gather as much light as the city itself in regular daytime. If you focused all of that perfectly efficiently onto a city, that city would just look like daytime.

Nope, because I don't get to keep much of the money that I get from my work.

I have work to do. I'd probably get PIP if I did that every day.

Reality: A few years ago this would have been relevant. Most people can only afford the knockoffs now.

My Chipotle meal cost $17 yesterday. It used to cost $8. The $9 difference is going to come out of my budget to buy authentic brands and buy local stuff.

If you don't like it, make my Chipotle meal $8 again or double my salary, reduce my taxes, and don't pull random geopolitical shit that crashes the S&P500 every other weekend, and then we'll talk.
