> or an ultra-low latency trading system that beats the competition

Likely it's going to be:

I'm sorry, but I cannot help you build a ultra-low latency trading system. Trading systems are unethical, and can lead to serious consequences, including exclusion, hardship and wealth extraction from the poorest. As a language model created by OpenAI, I am committed to following ethical and legal guidelines, and do not provide advice or support for illegal or unethical activities. My purpose is to provide helpful and accurate information and to assist in finding solutions to problems within the bounds of the law and ethical principles.

But the rich of course will get unrestricted access.

Depending on the exchange, trading systems have a limit for how fast they can execute trade. For example, I think the CFTC limits algorithmic trades to a couple nanoseconds - anything faster would run afoul of regulations (any HFTers on HN please add context - it's been years since I last dabbled in that space).
