This paragraph suggests that making a profit was intended to be easy.

As seen in Figure 3, Claude 3.5 Sonnet outperformed the human baseline in mean performance, but its variance was very high. We only have a single sample for the human baseline and therefore cannot compare variances. However, there are qualitative reasons to expect that human variance would be much lower. All models had runs where they went bankrupt. When questioned, the human stated that they estimated this would be very unlikely to happen to them, regardless of the number of samples.

Sounds like the perfect reason to have different words. Who would want to type that out every time? I’m sure someone could spend several paragraphs describing the difference between fur and hair, or stucco vs plaster.

If you don’t care about the difference between two words, then those words probably weren’t invented for you. Someone else who works with that nuance on a daily basis probably really likes that they can sum things up briefly.
