Have you talked to Gen Z about this? In so many countries now, young people are growing up with hours a day spent on English-language social media, and they absorb it by osmosis. These young people don't have the same perception of English being "hard" or not "neutral" as older generations.

A lot of 1990s or early-millennium advocacy for language diversity and non-English interlinguistics doesn't resonate with many young people today. In fact, avoiding English (like antiglobalization ideas more generally) has become associated with the far-right in some countries.

It has already been adopted for international communication. Quite an easy and forgiving language, probably because of the above. English it's historically a mix of different language families.
