While I can agree on the argument that rust offer many ergonomics and keep us away on many classes of security and memory management related issues. The quality of UX/DX is more defined by product and design requirements, not much to do with language of choice. Similar like restful api, good or bad is on the designer hand most of the time, not because it's implemented on some esoteric language.

OP said "devtime cost", ie, time to implement. They made no mention or insinuation of quality.

Yeah, but there's usually more time to put an emphasis on UX, as well as the fact that the ergonomics of the language again make it easier to implement the UX.
