If a control system's output is uncorrelated with what it is controlling, then it's not really controlling it. Also, to see a clear linear correlation, you might need to know what you're looking for. A controller output may look uncorrelated with the target system state, until you realize it's a I controller, so you need to look for correlation between controller's output and the integral of the system's state.

Let’s say there is a system that controls whether a second system receives input from random source A or random source B, and there is some difference in the distribution of values generated from each source. Starting without knowing the relationship between the two systems, is there a good general approach that could pick out what it is doing?

I'm still waiting for the startup that solves the burning problem of a lack of healthy food options in poor minority neighborhoods. A twice weekly food truck that offered fresh healthy produce and meats at reasonable prices would greatly improve health and well-being in those areas.

Aren't you worried that such a startup will run up against the same systemic biases that have been preventing poor minority neighborhoods from accessing healthy food at reasonable prices for decades? In other words, food truck entrepreneurs have been around for decades, so why doesn't the service you imagine exist yet? Because so far no one with the right motivation, i.e., no one with their heart in the right place,…

Translation: Keep your expensive stuff away from brown people. Kind of a disgusting attitude that isn’t acceptable for a business with aspirations of displacing personal cars. This happened in the 90s with rental cars. Organized insurance fraud (fake accidents with fake or overblown injuries) was incredibly rampant in Brooklyn, to the point that renting cars without significant deposits became difficult if you were f…

> Keep your expensive stuff away from brown people Why drag race into this? I’m sure the discussion was then same for concentrations of certain socioeconomic classes of people of any and all colors.

Perhaps it's time to repurpose all that time set aside for classical fiction literature to pick up some contemporary non-fiction.

Something from Steven Pinker maybe?

How is this "sharing?" This seems like app-based short term rentals little different from what I could get from Avis and the like. My initial thought was that this was allowing individuals to rent out their cars and my reaction was a hard 'oh hell no.' What's the term from the various "my expensive camera /lens was stolen" stories? Voluntary parting? Pretty sure that would apply to your nice car as well.

I still can't wrap my head around it why car rental companies like Hertz and Avis don't have this market completely cornered. They have the infrastructure, the assets, the know-how. Why is it still so inconvenient to get a car through them ?
