Like you, I am not a huge fan of JS, but I'd like to say that the ideas behind TermKit — namely having a shell with richer graphical interaction (e.g. cat works for images too), semantic awareness and tokenization of commands, rich autocomplete, etc. — were ahead of their time.
Maybe it's expected that TermKit-the-project died, but I don't think that TermKit-the-idea should: whether it be bringing features from the project as extensions to existing terminals (cat for images would be nice), or building a new TermKit built on modern graphics libraries powered by WASM/Lua/bring-your-own scripting language.
