I would really love an international language with consistent spelling and where the spelling matches the pronunciation. For me the chosen language doesn’t have to be artificial, but the selection process should be: a scientific choice based on consistency, ease of learning, clarity in meaning, … Everyone who knows a few languages, knows English is probably the worst choice when it comes to these objective criteria.

It’s like the system of measurement: leave it to the people and we’d all still be using wacky thumbs, feet and elbows for measuring, but smart people came together in France (a few times) and now we have an easy to understand consistent system of measurement.
