Ironically the physics are kind of my biggest criticism. They call these "world models", but I think it's more accurate to call them "video game models" because they employ "video game physics" rather than real world physics, among other things
It's getting better staggeringly fast, just a year ago I wouldn't expect it to be at even video game physics level so quickly.
If there is a possibility where it continue to improve at a similar rate with llms. A way to simulate fluid dynamics or structural dynamics with reasonable accuracy and speed can unlock much faster pace of innovation in the physical world. (And validated with rigorous scientific methods)
Numerical simulation is a well explored field, we know how to do all sorts of things, the issues lie rather in the tooling and robustness of it all put together (from geometry to numerical results) than in conceptual barriers. Finite Differences have existed since the 1700's! What hadn't for the longest time, is the computational power to crunch billions of operations per simulation.
A nice thing about numerical simulation from first principles, is it innately supports arbitrary speed/precision, that's in fact the backbone of the mathematical analysis for why it works.
In some cases, as is the case for CFD, we're actually mathematically screwed because you just have to resolve the small scales to get the macro dynamics. So the standard remains a kind of hack, which is to introduce additional equations (turbulence models) that steer the dynamics in place of the small (unresolved) scales. We know how to do better though (DNS), but it costs an arm and a leg (like years to milenia on a super computer).
I did the same thing and experienced the same effect.
I'd add that my ability to sleep naturally was negatively affected as side effect of medication. I tried a various combos to induce sleep and found the best solution to just be... exercise.
No caffeine, exercise, sleep lead to a significantly reduced anxiety and more.
It's because containers share the kernel with the host. Generally it's just not considered a security boundary. (Note that containers have come a longer way in the security side btw)
What about VMs? They offer strong isolation, as they don't share kernels, and have long been a foundational piece for multi-tenant computing. Then, why would we put an extra layer on top and rebrand it as an AI agent sandboxing solution? I'm genuinely curious what pushes everyone to build their own and launch here Is it one of those tarpit ideas: driven by own need and easy to build?
Depends. Probably not usually. I've thought about this a bunch and I think the serious "threat" here isn't the agent acting maliciously --- though agents will break out of non-hardened sandboxes! --- but rather them exposing some vulnerability that an actual human attacker exploits.
I'd also add that I just don't like the idea in principle that I should have to trust the agent not to act maliciously. If an agent can run rm -rf / in an extreme edge case, theoretically it could also execute a container escape.
Maybe vanishingly unlikely in practice, but it costs me almost nothing to use a VM just in case. It's not impossible that certain models turn out to be poorly behaved, that attackers successfully execute indirect prompt injection via malicious tutorials targeting coding agents, or that some shadowy figure runs a plausibly deniable attack against me through an LLM API.
security matters if want to demarc where agents can play. running agent inside of strong VM is usually where starts container not enough for that full isolation only sees files you want it to etc
we've considered docker, firecracker, will add smol to working roster
context <> building something with QEMU
* required has to support LMW+AI (linux/mac/windows + android/ios)
there are scenarios in which we might spin micro vms inside that main vm, which by default is almost always Debian Linux distro with high probability.
one scenario is say ETL vm and AI vm isolated for various things
curious why building another microVM other than sheer joy of building, what smol does better or different, why use smol, etc. (microVMs to avoid etc also fair game :)
In Chinese villages, I've seen them use fish skin, potato skin, various leaves, cooked birds nest, fish fin oil, and etc to treat open wounds instead of pure bandaging.
While it's not a new technique, it's fascinating for this area to be further explored.
It's important in these cases to preserve the lineage of where they came from.
There's a tendency to start calling them 'western medicine' and crediting it to the person who formalized it in the west rather than the source culture where it has existed for centuries.
The conversation is bit 2010, but the point still stands.
I can't even fathom what it would be like for the future of simulation and physical world when it gets far more accurate and realistic.
