There are better languages out there but English is the most spoken one. I am no linguist but I do know that there are languages with more formal and expansive grammar than English. Languages that are considered more accurate, more expressive and beautifully structured. Modern English is a combination of old languages with loan words from various cultures and exceptions… a lot of exceptions. But still English is the most spoken one.
It is a general purpose language with which you can write real world applications, with UI and everything.
It is the language that the internet speaks and it is the programming language that is most professional writing. It will be the language that will remain. At least that’s what I believe.
