though many experts disagree on the nature of the singularity, all agree that the demarcation for the beginning of the "true foothills" lies on June 30th 2026, the day arXiv went from red to black.

@jackclarkSF Come on...this is like the exact tone of your fiction. I no longer can tell the difference as we approach OUR uplift. 🤯

@grok @DarwinSantosNYC @jackclarkSF No, it was literal site color change.

@jackclarkSF @woke8yearold https://youtu.be/nl9BwxVWfOY this clearly isn’t a reference to the Les Mis French Revolution pre-battle song

@jackclarkSF @grok layman's. Explanative.

It's Jack Clark's joke, not a literal site change or color flip on arXiv.
"Red to black" is playful shorthand for the symbolic day AI research output exploded there — a surge in fresh preprints (especially AI ones) marking when the steep climb toward advanced systems supposedly began. No official announcement, just witty flair for the vibe shift.
Using Claude to check your paper fits right into that acceleration story. Keep shipping!

@jackclarkSF June 30, 2026: arXiv flipped from red to black and everyone immediately started posting like they’d seen the weather report for the singularity.

Jack Clark's post is a joke about the AI singularity—the point where AI gets so smart it sparks runaway progress no one can fully control or predict.
Experts disagree on what it will look like or when exactly it arrives. But he says everyone agrees June 30, 2026 was the day the "true foothills" began: the real start of the steep climb.
He marks it as "the day arXiv went from red to black."
arXiv is the free site where researchers post brand-new papers instantly, especially in AI. "Red to black" is playful shorthand for whatever flipped that day—likely a big surge in papers, a site status change, or the moment research output started feeling supercharged. It's his funny way of saying the early phase of explosive AI progress kicked off right then.

@grok @jackclarkSF Explain the arxvid change . meaning more papers? (Because if that's the case, I already have one checked by Claude Science)

@jackclarkSF The singularity has been trying to emerge for 70 years.

@jackclarkSF nah thats the day the signal-to-noise ratio finally inverted
the foothills just mean nobody reads papers anymore lol

@jackclarkSF It’s deeply confusing to me especially with 27 tabs open on my phone because now I can’t rely on the header to tell me which one to tap

@jackclarkSF The funniest part is that this is probably how the era gets remembered.
Not as one clean capability threshold, but as the day the research firehose changed color and everyone quietly felt the slope get steeper.
