So, I guess I'm leaving Bluesky. At least for the time being, maybe forever.
I left Twitter a few years ago despite having -I dare hope- a positive impact on Chess Twitter because of Musk, and because I was harassed, insulted, and threatened daily, mainly by far-right activists.

An umpteenth AI specialist acts against their own interest to warn us about the near-future AI threat to humanity, but most people here will shrug it away "it's called doom marketing!"
Another high profile resignation from leading AI company Anthropic. This is the warning to the world he wrote this evening on Twitter.
"The people building AI earnestly believe that it could kill us all by the end of the decade."

I once tought a class at a school to "never move your f-pawn"
Sure enough, when I let the kids play after the lesson, one of them played a similar f6??
I pretended to be like this 🥺
The kid, "what is it, Yosha?"
Me, "😢 you moved your f-pawn"
The kid, probably bluffed by my acting skills, went full 😭

yeah i saw that and had a flashback to maggie playing 3.bb5 h5 against me in one of the first iterations of the magnus tour 2020, and how much indignation it produced (not from me, to be clear). in hindsight, that was a show of respect, at least compared to this ;)
Huh?

Fun fact:
Marcel Duchamp left art to become a chess player.
He also had a female alter-ego, Rrose Sélavy, who had her own artistic career and often met friends or went out in Paris, even late in life.

Madame Chaudé was a pionneer breaker of gender barriers in chess. The first women to play in the then "Men's" Olympiad, and a regular in the overall French Championship.
She acquired legend status in her lifetime and I'll always remember her kind words to confort me after a tough loss when I was 10.

Some @chess.com employee deserves a pay raise for the 'even my friends don't text me back that fast' joke, but also a pay cut for saying you need to map all chess games to solve chess.
You just need every position (~10^45), all their legal moves, and the result (win, draw, loss) associated.

People on the left need to wake up to the potential of AI, because denying its capabilities ("It's just a tool", "It's just a stochastic parrot") means denying its biggest risks.
Yes, the ecological impact of AI is a problem, but it's far from the only one.

A lot of people on here are consistently downplaying the risks here or ignoring it. I think that's a big mistake.

In case someone is wondering, the answers are
1. No, at least one of the kings has already moved because a pawn has necessarily been promoted on f1 or f8
2. The parity shows it's black to move, hence 1... Nxf2# (it's a known concept, might have been one of Raymond Smullyan's originally?)

My two cents on chess benchmarks: the best way to test AI's 'intelligence' using chess is via unpublished retro-analysis problems like these:
1st diag: White to move, can the game continue with 1.O-O O-O
2nd diag: Who is to move? Mate in 1?

With some luck, I somehow managed to qualify for the semi final.
Huge congrats to Sophie for a well deserved 7th (!!) title!

The E-sports World Cup qualifier was a strong tournament! Before the last round I thought, oh if I win against someone weaker, I can't qualify but might win $1.500
I was paired against Grischuk... got a winning position (played Bxc5! +2 here) but lost.
At least I made a solid draw against Leko!
