I think the language problem will become less of a problem in the future due to (1) more (young) people living in citys and (2) all young people in cities speaking english. At least compared to previous generations imo. This could be my subjective view based on luxembourg, netherlands, and visiting other european cities.
Don't overestimate "young people speaking english" especially with current demography you still need to tap ones that are excluded from English as there will be much more of those.
I do see opportunities with LLMs as making all kind of platforms language agnostic - you should be able to write your own language and read your own language even if other person is from different country using different language.
