English is now the default medium of international business, science and travel. I regard this development as overwhelmingly positive, because a shared language accelerates global cooperation and expands opportunities for individuals everywhere.
The first benefit is collective: a common tongue removes friction from international exchange. Scientists publish and collaborate across borders instantly; pilots, doctors and engineers share safety standards without translation; and global responses to crises — pandemics, climate negotiations — move faster when everyone can negotiate directly. Knowledge that once stopped at national frontiers now circulates worldwide within hours, accelerating innovation for everyone’s benefit. The COVID-19 pandemic illustrated the point: vaccines emerged in record time partly because laboratories on every continent could share findings instantly in a common language.
The second benefit is personal: English functions as a passport to opportunity. A young Vietnamese or Brazilian who masters it can study at foreign universities, work for multinational companies or sell to customers on every continent without leaving home. Critics worry that global English endangers smaller languages, but the two can coexist: most learners add English to their mother tongue rather than replacing it, as bilingual societies such as the Netherlands and Singapore demonstrate. The realistic choice facing most people is not between English and their own language, but between connection and isolation. Vietnam's own boom in outsourcing and tourism owes much to its English-speaking young workforce.
In conclusion, the rise of English as a global language is a positive development: it binds the world’s knowledge together and gives individuals unprecedented access to education and employment. Societies should embrace it while continuing to nurture their native languages. Fluency in it has quietly become part of what opportunity itself means.
