Do people that know a lot about LLMs tend to go a little insane or are people who are a little insane more likely to know a lot about LLMs?

My only issue so far is that companions don't render properly.
Mu fox companion on the android app. Looks compressed and has an artifact at the top.Mu web app companion in the same pose. Pixels look sharp

I think the breakthroughs will be limited to things that require only compute to be tested. Applied physics, biology and chemistry will be bottlenecked by needing actual physical experimental setups.

I seriously fail to see the problem. The actual translation work, the artistic aspect was fully human made. They only used AI to actually make it run, because modding old games is the kind of tedious work LLMs excel at.

so sick of AI / fluid dynamics discourse on this app; now to relax with a big swig of hot milky tea
GPT-5.6: This is actually a lovely everyday visualization of Navier–Stokes.

The coffee and cream are fluids with a velocity field \mathbf u(\mathbf x,t): at every point in the cup, the liquid has some direction and speed. Navier–Stokes describes how that field evolves,

\rho\left(\frac{\partial \mathbf u}{\partial t}+\mathbf u\cdot\nabla\mathbf u\right)
= -\nabla p+\mu\nabla^2\mathbf u+\mathbf f.

In the photograph you can almost assign each term a visible role:

* \mathbf u\cdot\nabla\mathbf u: advection/inertia. The curling cream filaments reveal parcels of liquid being swept around by the existing circulation. Their folds and tendrils are basically tracers of the hidden velocity field.
* -\nabla p: pressure forces. Pressure gradients help establish and redirect the circulating flow, especially after pouring or stirring.
* \mu\nabla^2\mathbf u: viscosity. This damps sharp differences in velocity. The whorls don’t keep getting faster and finer forever; their kinetic energy dissipates and the coffee eventually becomes still.
* \mathbf f: body forces, especially gravity/buoyancy. If the cream and coffee differ in density or temperature, buoyancy can generate some of the rising and sinking plumes.

There is one nice wrinkle: Navier–Stokes itself does not directly describe the changing cream color. The cream concentration c is approximately a passive scalar obeying an advection–diffusion equation

\frac{\partial c}{\partial t}+\mathbf u\cdot\nabla c
= D\nabla^2 c.

So the spectacular visible swirls are the cream making the invisible Navier–Stokes velocity field visible. Advection stretches the cream into long thin sheets; molecular diffusion then mixes efficiently across those increasingly narrow sheets.

The picture therefore captures a central fluid-dynamical idea very well: flow creates structure at large scales, stretching and folding pushes it toward smaller scales, and viscosity/diffusion ultimately erase it.This is actually a lovely everyday visualization of Navier–Stokes.

There's been reports of a bank run in Russia, but the only reputable outlet I've seen post about it has it paywalled. www.washingtonpost.com/world/2026/0... Is it as widespread as the headlines make it seem?

Russians pull billions from banks, fearing Kremlin will seize deposits for war
Russians are withdrawing billions, causing liquidity problems for banks and undermining the Kremlin’s ability to issue bonds to finance the fight in Ukraine.
