In the end programming languages are tools, and tools are often designed to fit well in the existing ecosystem. E.g. python is “easy to type”, thus designed for the keyboard “meta”. Similarly, if one designs a language with synergy with LLMs in mind, it may yield productivity boosts.

For example, one could conceive a language that is very safe, but to achieve this it may perhaps also be very verbose. Such a language may be horrid for humans, but perhaps fine for LLMs.
