A remarkable dynamical symmetry of the Landau problem
We show that the dynamical group of an electron in a constant magnetic field is the group of symplectomorphisms $Sp(4,\mathbb{R})$. It is generated by the spinorial realization of the conformal algebra $\mathfrak{so}(2,3)$ considered in Dirac's seminal paper "A Remarkable Representation of the 3 + 2 de Sitter Group". The symplectic group $Sp(4,\mathbb{R})$ is the double covering of the conformal group $SO(2,3)$ of 2+1 dimensional Minkowski spacetime which is in turn the dynamical group of a hyd…

There has long been a quiet debate, currently drowned out but still very much happening, about human replacement vs human augmentation. Think of Gary Kasparov remarking years ago that he thought chess played by humans with computer assistance could be a far more interesting game than either human-only or computer-only chess.
Here’s an argument for augmentation over automation, and note how far it diverges from the current hype despite it being written from a very AI-friendly point of view:

I dreamt last night that I was in Glasgow for a concert and a massive power failure occurred. There was no electricity and all electronics were fried - radio, phones, internet, nothing working except some very old cars with no electronic systems.
We heard rumours that either the Earth had been hit by an EMP pulse from a cosmic event, or maybe this was more local and was caused by a weapon of some kind.
Police were out on horseback telling us to stay calm but had no info. /1

„Tensions erupted at the Rafah crossing as local Egyptians confronted far-left Western activists— described as "Greta Thunberg types" —who had gathered to "march on Gaza" and protest against Israel.
The mostly European demonstrators, accusing Israel of
"genocide," were met with fierce opposition from Egyptian locals, who pelted them with clubs and water bottles, forcing them back and halting their advance toward the border.“

Jewish Breaking News on Instagram: "🇪🇬😱Chaos Erupts in Egypt as Locals Clash with Western Pro-Ham@s Activists Near Gaza Border BREAKING: Tensions erupted at the Rafah crossing as local Egyptians confronted far-left Western activists—described as “Greta Thunberg types”—who had gathered to “march on Gaza” and protest against Israel. The mostly European demonstrators, accusing Israel of “genocide,” were met with fierce opposition from Egyptian locals, who pelted them with clubs and water bottles, forcing them back and halting their advance toward the border. Many of the activists have since taken to social media claiming they were beaten, had their passports stolen, and are now stranded in Egypt. Several are pleading online for help from their embassies. One Egyptian pundit remarked: “There’s a reason Egypt has a huge wall and doesn’t let any Gazans in. What made these people think they could just ‘march to Gaza’ via Egypt?” Egyptian authorities have yet to issue an official statement."

Saints' Chris Olave downplays concussion concerns, trade rumors: 'I want to be here forever'

I see @… has a similar reaction about a study that says something we want to hear.
Re that second remark, “The *point* of AI is to make cognitive abilities irrelevant,” well, that’s the thing that’s up for debate right now. Making cognitive abilities (and thus labor, and people) irrelevant is very much the marketing pitch of the hype bubble. That pitch is about cost cutting, and about fear and intimidation — an intoxicating, investor-frothing mixture of fantasy and terror.
It’s not the only vision of AI, however.

Near-extremal holographic charge correlators
We analytically compute the low-temperature charge correlators in near-extremal black holes with a planar horizon and an infrared $\mathrm{AdS}_2\times \Bbb{R}^2$ extremal geometry, finding excellent agreement with numerical calculations. The analytical result consistently describes the crossover between the hydrodynamic diffusive regime at low frequencies and wavenumbers, and the quantum, zero-temperature regime at high frequencies and wavenumbers. We analytically resolve the successive collis…
