There isn't going to be a lot of improvement in overall EV performance/capability from better motors. Existing, boring motors are already close to 100% efficient, already small, and already powerful.

Advancements here chip away at margins, its nice but nothing to get super excited about. Whereas a modest ~20% increase in energy density from batteries would be amazing. Every little bit we improve there unlocks new capabilities. Towing long distances, smaller affordable economy cars and sports cars, airplanes, etc.

In countries where students perform better, they do the opposite of your plan. Resources are pumped into the failing schools to get them to do better. You seem to be just arguing for even more privatization in American which is awful, the kids that are failing have parents that won't be paying for good education or setting up schools. They won't bother with it at all if it isn't public and required.

Nate was a huge outlier in that prediction, he gave trump a better chance than almost anyone else that I can recall, so why are you mad at him about that?

What made me mad is Nate seemed to turn into a MAGA troll himself after that election.

Why does anyone want to work for companies run by such awful people in the first place? I saw me CEO make up a whole new persona to suck up the new nazi administration I would be gone the next day.

I recently started a game project in Rust aided by Claude Code because I asked myself that same question. I like Rust, but it is definitely harder than C# for me. But with the AI aid, doesn't seem to matter which language I use. So I take the performance and safety wins.

With some care about what features to use and when, F# can be very fast. Which is nice, use functional paradigm when you want, or low level imperative code in hot loops if you need. But yeah if you use linked lists and sequences and immutable data types everywhere it sure isn't Rust.

I think you are right that we should focus on the fact that the president raped children, invaded Iran with no plan and for no reason when he promised not to start a war, and violates the constitution and law daily without consequence.

We are all failing morally for not revolting at this level of corruption.

He raped kids and the entire GOP is helping to cover that up.

The disingenuous people who discredit climate change will do so no matter how serious people act. There is no point in changing behavior on their account.

Yes, our tech leaders would rather send america into fascism that have any impediments put in the way of their business plans. It is disgusting, and sad.

>It's physically not possible at our current level of technology to make this "safer"

Absolutely it is, if NASA was not constrained by congress to use shuttle components to build the spacecraft, they could have had double the payload mass capability at least (the Saturn V was almost twice as capable, we should be able to do a little better now). This would provide tons of extra margin for safety, and allow a shorter and thus safer route to the moon as well.

We are not in a democratic setting in America any more, the people in power are willing to start wars to protect pedophiles, they are willing to hire Nazi thugs to shoot your wives in the face. They are willing to bribe supreme court justices and dismantle democracy, and they will if not stopped by force.

Thiel has been obviously and evil sack of shit for decades but more than half of HN viewers revere him. I fear we have no hope, and the good people asking how we can democratically solve this problem makes me feel even more hopeless. Yall don't get it.

oh, paul grahams eassays!

Speaking of, how are his efforts to help this administration cut down no woke youth?

Does he still think racism isn't as bad a "the left" thinks, after Elon's Nazi salute and the thousands of ICE agents brutalized immigrants, murdered citizens, while cheered on by half the country, then invaded Iran because the Christian right thinks its a holy war against Muslims?

The racing frames here don't break as a rule as OP suggests, if one does there was a manufacturing flaw or a crash/impact of some kind.

A few grams of weight does not have enough impact TT bike performance enough to make it worth shaving 100 grams if it risks reliability.

There used to be a video on youtube of a carbon mountain bike fork, and they were SMASHING it with a ball peen hammer, repeatedly. It did do a little damage but remained rideable, and was in much better shape than the metal forks they smashed.

This has no practical impact on actual bicycles though, in practice they all fail, at similar rates.

Yes there is, I and many people have directly measured it.
