Lot of mad people around these parts, sure, but blue tick media accounts coming on here to whine about how they’re not praised enough to make it worth cross-posting on BSky is not exactly a great look. You have to make at least a modicum of effort on a social platform to build the audience you want.

I hope this is a short-term mistake, but it’s definitely a huge mistake.
“The U.S. no longer has emission standards of any meaning,” said Margo T. Oge, who served as the E.P.A.’s top vehicle emissions regulator under three presidents and has since advised both automakers and environmental groups…
“Nothing. Zero,” she added. “Not many countries have zero.”

Have you ridden the new Acela trains?
I'm finally on one, business class (quiet car, my usual). My first take is that it's way more cramped than the old Acela.
It's definitely a higher-tech experience, but so far it doesn't really feel like a premium experience.

I think this is my view on "AI" right now:
AI is radium. AI is hydrocortisone.
Both eventually turned out to be very useful in certain circumstances. But the initial urge to put them in everything created a lot of disasters -- and the backlash wasn't great either.

If you want people to be 'reasonable' about a subject, I highly recommend not stealing from them, attempting to coerce them into using a mutilated mockery of their own stolen goods and then sniggering that this will ruin their livelihood.

Explanations?
1) Incriminating Epstein documents being circulated internally
2) Illegal activities discovered in the business
3) Extraordinary coincidence

Of course the real reason turns out to be deeply stupid.
This can be read as the Pentagon refusing to deconflict airspace, so the FAA arguably is doing the right thing, though others who are more expert on this should weigh in. cc @faineg.bsky.social
