Each of the languages you mention are very small deltas (relatively) from our current state of the art (some more than others). It's not hard to convince one of the benefits of such languages, because they are already anchored. e.g. X language is like Y but with Types. Or, W language is like Z but with pure functions. etc.

Eve was very different from any language in widespread adoption, to the point where using it didn't even feel like programming at times. Therefore, it was difficult to quantify the benefits to others (especially companies) who have not experienced them first hand. With Eve, we didn't even know the full scope of supposed benefits until we started actually using the system we imagined in our heads.
