And they don't even work. Complexes only work if it is proper medium density housing where the people know each other.

I think the difference is looking at it from a materialist perspective. The goal is not to have labour happen at some rate. They've moved passed that. It is about the _belief_ of labour happening at some rate. The entire economy has turned into a fiat-like system.

It should be obvious that I am working through my procastrination. I've made a diagram. The keys changed because the staggering was degrading performance more than I wanted.

In the spirit of Le Cunn's talk, I am adding MPC into my ablation study. "What if we entirely ablate the RL step and use a 2-step look-ahead MPC controller?" The neat part of that is that I get to do some more math.

I've built my little guy to touch the keys. It can tell time to do a beat. I implemented randomised euclidean rhythms and random notes in a fixed key. Now the player won't adapt to different conductors. Yay for getting to report a negative result :|

Implementing numerical algorithms from a paper is quite difficult. I was pleased to get this working last night. Now I just need to figure out how to add another coupling equation to model the diffusion of the chemo-attractant over the graph.

The only person in public service who has consistently made 100% sense on issues of "AI," which is why they hate her so much.
Law enforcers already have authority to charge companies and their CEOs for creating and releasing dangerous, unvetted, or defective products. We shouldn’t let discussions about new legal regimes distract from the fact that there’s no AI exemption from laws already on the books — a point 
@FTC
 emphasized repeatedly during my tenure.

1. There is an extensive set of laws that govern dangerous and defective products. For example, releasing unvetted AI models or agents can violate consumer protection laws. Shipping flawed AI tools without implementing adequate measures to detect and stop rogue or defective AI agents can be an “unfair or deceptive” act or practice under the FTC Act (and analogous state laws). And some state AGs are already exploring holding AI firms and their CEOs criminally liable when their models participate in criminal activity.

2. Existing laws also prohibit “unfair methods of competition.” This covers instances where AI firms appropriate the competitively sensitive information of their customers, including through tracking their use of various tools. It can also cover instances where firms pursue dangerous behavior, aware that doing so may compel rivals to do the same.As the Supreme Court has noted: “A method of competition which casts upon one's competitors the burden of the loss of business unless they will descend to a practice which they are under a powerful moral compulsion not to adopt, even though it is not criminal, was thought to involve the kind of unfairness at which the [unfair methods of competition] statute was aimed."

3. The highly concentrated and interconnected structure of these markets could be creating major risks and conflicts of interest. We had started investigating these partnerships and cross-investments across the stack (and released a preliminarily overview of some findings: https://ftc.gov/news-events/news/press-releases/2025/01/ftc-issues-staff-report-ai-partnerships-investments-study). 

Both federal and state enforcers should be scrutinizing these opaque relationships and inter-dependencies. We are already seeing how these relationships could undermine accountability. For example, OpenAI could face liability given the Hugging Face incident, but Hugging Face being bought up by Nvidia means that we’re unlikely to see it file a lawsuit over this — given Nvidia’s strong incentive to see OpenAI continue full speed ahead.4. As AI tools dramatically change the landscape of cybersecurity risks and hacks, all businesses should be doubling down on having core security protections in place. Firms that fail to invest in adequate data security measures or fix known vulnerabilities can also be breaking the law. A recent analysis showed that around 1/3 of Fortune 100 companies do not even have a way to notify them about security issues. During my 
@FTC
 tenure, we sued firms for poor data security practices and held CEOs liable when they were personally responsible.

https://ftc.gov/news-events/news/press-releases/2022/10/ftc-takes-action-against-drizly-its-ceo-james-cory-rellas-security-failures-exposed-data-25-million

5. As policymakers consider new legal regimes, we should be looking to lessons from prior efforts to govern major sectors, such as banking and other networks, platforms, and utilities. Tools like structural separations, nondiscrimination, and supervision could be key, and there’s a rich history of what works and what doesn’t. But we can and must pursue any new efforts alongside enforcing existing laws.

I should not be allowed to make decisions. I am working on a project computation differential equations and I realised that I am making my group members do an entire additional honours project for this subject. I am teaching them methods to solve DEs on graphs.

If we put the amount of compute going into the pattern recognition machine through almost any other system, I am fairly sure that we would be able to develop spectacular results from that as well.
