Extending a state with additional variables doesn't make a unique state less unique anyway, so "total state" is always more or same unique as "just tape".

This is really not a limit because of unified memory -- in principle, PCIe GPUs could read/write main memory without the CPU. But it's a limit for /fast/ unified memory, because fast means close.

So unified memory is great as long as the integrated GPU is strong enough. Then it has two advantages: a) probably faster transfer CPU<->GPU (but that's an implementation choice for the non-unified case b) If you either need a lot of memory for the CPU or the GPU, but not for both at the same time, you pay for memory only once.

Is a non-well-aligned frontier level AI a problem? I think it is likely that it is, or at least has a high likelihood to be in the future. Two scenarios for this: Misused by some bad guys. Or the terminator scenario. Both not great.

So what do we do about it?

1) We can accept it, and hope that the good guys AI can defend.

2) We can try to limit the access to it (AI proliferation?)

3) We stop the development of it

4) We can accept the risk and do nothing.

None are particular good options. Really reminds me of nuclear proliferation, on so many levels. For that, we kinda do all three:

1) Nuclear triad / iron dome / early warning systems

2) Nuclear anti-proliferation treaties.

3) Dead Physicists

Ok, so assuming all of this is true, open weights are a problem. Don't get me wrong, I love open science, open source etc. It's great to have access to capable open models. But: Even if release open weights are well aligned and have a safety layer built in, it is likely not to difficult to abliterate that part of it.

If this is really where it is going, then even closed weight model providers will see a lot more requirements for protection of the weights.

a) People do bad stuff because LLM told them a wrong thing. Example: AI told me I should treat my heart attack by putting a fork in the outlet. Maybe similar to seeking medical advice on reddit?

b) People use LLM to do bad stuff. Example: People use LLMs to find 0 days. Get cooking recipes for poison. Write better phishing letters. This has parallels to the gun legislation question.

c) LLMs do bad stuff on their own, beyond what the people that use it intended. The case at hand might be an example of this. Maybe similar to having an animal as a pet. We will see if it's more like a house cat, lion, or black plague.
