Documentation and testing used to be mildly important, you better have them, but the quality of the tests didn't matter as much, since you have to get the implementation right, no matter how good or bad your tests are.

Now that the work is delegated to an LLM, the test and documentation quality ultimately decides the quality of the product.

Since you as the programmer no longer have to deal with the language's annoyances directly and force the LLM to perform the drudgery for you, you can build a language that makes a trade off between drudgery and quality and receive a software quality upgrade essentially for free.

LLMs are really good at producing tokens faster than developers, so make those tokens count.
