I'd like to point out that even though it took them a week compared to an hour, a week is actually incredibly fast to learn Rust and build something useful with it. Learning C++ can take more than a month of training, and it's only because most people learn it over an entire semester at school that they learn it at all. This is also the time it takes to learn Rust, and presumably now that they've written one program, writing the next program will take them a fraction of a week. The amount of time it takes to learn something is often indicative of its power. Anyone who has learned a foreign language or a musical instrument knows that the time spent investing up front pays huge dividends down the road when you have the skills and tools to richly express yourself. The reason that Go takes two days to learn is because it artificially limits the amount of up front investment at the cost of limiting expressiveness over the lifetime of your use of the language.

Learning any of C, C++, Rust or other systems languages takes way, way more than a week or a month. For C, the simplest of the three, it is usually rated at 3 months. What happens is that if you are already proficient in one of them, one of the others takes way less time (specially in the case of C++, given it forces you to learn almost all paradigms). In addition, writing a small program does not mean you have learnt C, C++ or Rust.

I would argue that something that takes even an experienced engineer a mere hour to write is very small and has little complexity (especially if unit tests are counted towards the hour it took them to re-write it). This means it's difficult to gauge how much Rust was 'learned' during that week.
