I personally would be angry if English became the universal language.
"Would". I'm afraid you don't have much of a choice. The fact that you are using this language now (the official/
de facto official language of air traffic, maritime law, medicine, science, commerce, the internet, banking, as well as numerous other international organization) is telling enough of where the momentum is going and where it will end.
People who site the erstwhile importance of Latin or French fail to include the fact that those languages were the purview of the powerful class and were nonetheless spoke marginally. Go to Haiti, the Congo or Vietnam (nations hardly considered wealthy) and you'll find even the poorest kids regurgitating English quotes, sayings and greetings. Those who site the "upcoming" importance of Chinese (the only possible competitor) fail to understand that China isn't exporting Chinese. No one in Africa, Latin America or Europe is learning Chinese. In a world where there is only so much room on sudents' plates for second languages, there is only one language to learn: English.
English is taught in every classroom (well, those worth their salt) from Calcutta to Nairobi; Buenos Aires to Beijing. In places like China, India, Germany, Brazil (even with its close interactions with the Spanish Latin America) and Russia, there is no "other" second language. Every kid knows: if you want to make it in business, entertainment, politics or the sciences, you need to learn English. It has co-official status in the soon-to-be most populous nation on Earth: India, and is obsessively taught in the current most populous: China.
Momentum, especially for 6.5 billion people--with infrastructure to boot--is unimaginably difficult to shift and unless interstellar invaders change our current course, there is little possibility of any other language usurping English.
English is confusing and difficult, not to mention it's totally bland and unimpressive sounding imho.
If you find it bland, then you don't speak it well enough. I am bilingual--by choice--and while I find Spanish to be beautiful, I find it to be nowhere near as versatile as English (though, satisfyingly more efficient).
