The weird thing is they mostly aren't all that rare, it's just that China has been spending decades putting arrangements in place so it controls many of the major supplies. Unfortunately, western governments don't look that far ahead.

Yeah, it's, uh, something! 😂 Jensen's is very nice, though. Trump's is full-on American Psycho, which is appropriate.

To have a song like this come from the biggest band in the world is just incredible, too - kicking open the door musically for sure!

The conference included AI from just about every angle, so not all Gen-AI, Vee. The one thing that can stand up to whatever issues one sees wrt generative AI is people - but I don't think most people actually care enough to make a difference. Human beings are devolving to be hopefully tech addicted.

The conference was definitely about a lot more than just generative AI, if that's what you're talking about (though not really clear what you're talking about)

Yeah, such a bizarre song! I'm a bassist, so those chord changes are my life (and pretty hard to figure out on the fly given the strange harmonic movement in thirds) 😁
000
Jeff MacArthur @jeffmacarthur.bsky.social · 24/09/2026
Is it really jazz sheet music if it doesn’t have chord changes above the bars? Trick question, the answer is obviously “no”. 😆

That's pretty much the definition of privilege or ignorance or both. Would be nice to live in a world where politicians' dumb decisions didn't impact me.

Absolute banger of a song, which is even more amazing given that it’s in 13/8 time for the hook

Okay, Don, I'm sure all of those big AI companies will be eagerly following your brainless lead relative to your impotent renaming fetish in no time.🙄 Do people who vote for this guy understand that he should be, you know, doing REAL work instead of this nonsense? Pathetic.

Lots of non-Nazi folks still on Twitter, obviously, just like lots of non-MAGA folks in the US. I feel the reference also requires me suggesting the fantastic 'Allo 'Allo! TV series, which is literally about waiting out the end of WWII in a Nazi bar in France.😀 en.wikipedia.org/wiki/%27Allo...!

I justify it by the fact that I (& many of the people I'm closest with there) was on Twitter before Elon Musk ever got there. It's OURS, not his. I think the same question could be asked of people who have not left the US once Trump was re-elected (& I think my answer would apply there as well).
