My guess (nothing more, thank you
)
Alizée will reach beyond her cult following outside of France and Europe. But she will always be one of those artists who 'should be more popular.' Many people will continue to discover her regardless of how much music she produces. There will be another extended hiatus in the next 10 years.
She will eventually mentor another young artist, cameo in movies but not 'go into' acting, and become involved in politics in a substantive and non 'celebrity-does-activism way'.
