>> What would constitute a "good" programming language for embedded systems?

"Good" for what purpose? That is, what are the goals, requirements, and limitations of the target embedded system? If the system fails or encounters errors, what is the worst outcome?

C and C++ are the most widely used and supported. Rust is up and coming in terms of support, features, and popularity. Ada works great and is required for some embedded applications.

>> overall what would constitute a good PL for this domain?

Most embedded systems have limited hardware (slow or low power processor, minimal RAM, minimal storage, etc.) and will have either a minimal real-time operating system (RTOS) or no operating system running on bare metal.

A good programming language for embedded work will be able to interface directly with hardware, run fast, and use minimal memory.
