There are still enthusiasts of alt/inter-langs, more modern than Esperanto, which only has european roots - I prefer those that also blend in words from Chinese, Hindi, Arabic etc.
See also this community .
However modern technology - such as instant translation built into phones (very useful for Ukrainian-French here last year) - changes the situation, maybe diminishes the motivation to learn such languages, although potentially facilitating their use.
Thanks for post, would be helpful to see more context, like how much did each change?
