This seems like an example of something you can in fact get paid for if you are as good as you claim. In the past 15 years Flutter/Dart, Rust, Kotlin  were created and if you can build a language that is as good as that you will be able to get income via consulting, working at companies, and donations. Most start ups/new projects will not get you paid immediately but you need to have a plan for how you will get paid (and the tolerance to work long enough to see that outcome).

The Plague of Justinian is possibly responsible for the failure of the Roman Empire to reunite (Justinian had reconquered Italy and if he was able to secure those holdings European history might look more like Chinese history). Later iterations of the plague might have been responsible for the rise of the Muslim empires. https://en.wikipedia.org/wiki/Plague_of_Justinian https://pubmed.ncbi.nlm.nih.gov/22992565/
