The WI Supreme Court consists of 7 justices who are elected to a 10 year term in a "nonpartisan" (though definitely partisan) election. They are the highest appellate court in state law and deal with issues related to the state constitution. Their decisions can be appealed to a federal court if it is in conflict with the federal Constitution, but otherwise, it would be the last court of appeal.
Of particular note are cases dealing with electoral law and districting. Wisconsin has been considered the most gerrymandered state in the union since about 2010, and it's led to situations where Republicans secured a supermajority in the assembly despite receiving a minority of the votes. The right-leaning Supreme Court dismissed challenges to these maps and allowed Republicans to enact laws that entrenched their power in the state (such as unfair electoral maps, restrictive voter ID laws, and removing powers from the governor after a Democrat was elected). Swinging the Court to the left is seen as the best hope of restoring fairness to our elections.
I was finally playing around with it for some coding stuff. At first, I was playing around with building the starts of a chess engine, and it did ok for a quick and dirty implementation. It was cool that it could create a zip file with the project files that it was generating, but it couldn't populate it with some of the earlier prompts. Overall, it didn't seem that worthwhile for me (as an experienced software engineer who doesn't have issues starting projects).
I then uploaded a file from a chess engine that I had already implemented and asked for a code review, and that went better. It identified two minor bugs and was able to explain what the code did. It was also able to generate some other code to make use of this class. When I asked if there were some existing projects that I could have referenced instead of writing this myself, it pointed out a couple others and explained the ways they differed. For code review, it seemed like a useful tool.
I then asked it for help with a math problem that I had been working on related to a different project. It came up with a way to solve it using dynamic programming, and then I asked it to work through a few examples. At one point, it returned numbers that were far too large, so I asked about how many cases were excluded by the rules. In the response, it showed a realization that something was incorrect, so it gave a new version of the code that corrected the issue. For this one, it was interesting to see it correct its mistake, but it ultimately still relied on me catching it.
