How likely is it that, in the future, everyone in the world will be subject to the same laws?

I'd say it's quite unlikely we'll have universal global laws anytime soon, mainly because legal systems reflect deep cultural differences that can't be easily reconciled. For example, here in Shanghai, we have strict internet regulations that wouldn't make sense in countries with completely different values around free speech. Even within China, local governments sometimes adapt national laws to fit regional needs - like how Hangzhou implemented stricter environmental policies than other cities. That said, we might see more international agreements on specific issues like climate change, where shared interests outweigh differences. But complete legal uniformity? That would ignore how laws grow from a society's unique history and priorities.
