I've been wondering if Java would have a resurgence due to strong typing even into the error types, and widespread runtime availability. But so far, seems no.

Ease of understanding; JavaScript. That was literally its design goal; JS might have a whole lot of bad parts but it's flexible and easy to understand.

This is the complete opposite of how LLMs are trained. LLMs are most effectively prompted (for instruct/chat finetunes anyway, i.e. chatbots) through the same kind of language patterns (natural or formal/programming) that they learn from. Trying to write formal prompts to them is exactly as misguided as speaking to your friends and family in C.
