You know what AI is decent at? Pattern recognition. So, it would be good at funding the same things that have been always been funded. That's not how we get the next cutting edge discoveries. That's not a meritocracy, that's legacy admissions.

Charts show the activity of local, regional and long-haul trucks by time of day, largely parked (on average 56% of the time on weekdays for long-haul trucks, with a minimum of 40%. 90% of time for local trucks on weekends).

The reason why EVs are such a great opportunity for a renewables-based power system (or any power system, for that matter), and why we need universal charging while parked: cars, and even heavy-duty vehicles: parked most of the time > demand flexibility through smart charging!

That's up to 10,000 minutes per year, excluding any evening or weekend trips. 170 hours β€” a full week. Multiplied by hundreds of thousands or millions of people.

A month into congestion pricing and my bus commute into NYC is consistently 15-20 min faster each way, no matter what time of day I travel. It has given me 40 minutes of my life back. I work in midtown and crossing the street is no longer gridlock.

Comparison of per-capita road-transport emissions in selected countries.
β–ΈNorway has made great strides in turning its passenger-car fleet over to battery-electric, with >90% of new cars BEV, and share of the car fleet passing 27%.
But doesn't have the lowest road-transport emissions per capita. 1/2

To me this is a root cause of the crisis. We've continuously failed to prosecute people who are powerful.

Inevitably the law breaking just escalates. It's true of both Trump and Musk. Their shameless criminals. And it's true of many who've given them significant financial support.

A pretty simple way to exemplify America First.
Maybe even a grudge with Bill Gates?
Test case on how to illegally dismantle a government agency? And test the public reaction?

Problem: these folks are too rich and powerful to care about any hits to profits. They are preoccupied conquering the next frontiers of space, AI, etc., buying elections, destroying regulatory systems/governments/democracies. And most of them can basically conjure money.

Trump Has A Plan To Sabotage The Government β€” And It Worked Perfectly His First Term The first Trump administration's strategy caused a "brain drain" and a generational blow to American agricultural research. And Trump’s not finished.

During Trump's first term, the USDA gave hundreds of expert agricultural economists and researchers an ultimatum: Relocate across the country on a few weeks' notice,Β or lose your job. The results were devastating – a generational brain drain. Trump's not done.

The point is to destroy the process. Even if in 3 months the SCOTUS decides this case, the damage is done. In a week Trump has exposed our entire legal and governmental system as a joke. We’ve been dealing on the basis of trust for the last 250 years. Just stupid.

Chris Rufo literally told us this 1.5 years ago. I took this screenshot. Media never gave a fuck even though he openly admits everything he does. He also fabricated the CRT panic from a while back and admits it on his twitter, too. Also that he wants to destroy gains from the civil rights movement

How quick is quickly? In the meantime, would courts be able to block or cancel OMB's guidance? And how would agencies react?

Any hope of stopping the "temporary" chaos and harm?
