I don't think we'll ever have one universal language, simply because languages tend to change and fragment over time. If we ever did have a universal language, English would be the worst choice possible as it's incredibly complex to learn.
This. All the native English speakers will think of it as normal, but English is incredibly screwed up when it comes to inconsistencies and downright ridiculousness. Probably something to do with the fact that it's a meld of about 5 major languages and god knows how many smaller ones and subdialects.
Can't remember specifics, but my French teacher used to say that English grammar is extremely convoluted - it's just that native speakers somewhat instinctively learn the distinctions. I think that broadly this is what they were talking about:

English is actually one of the easier languages to learn. Together with Spanish and...one or two more I believe. In contrast Chinese and Dutch, for instance, are very difficult languages. English is already the go-to language in Science, travel, business, computer technology and the internet. There are also already quite a few western countries where English is mandatory in school. (My country being one of them.) Why not slowly extend that to the entire world over the next...say...25~50 years? I'm not talking about learning fluent English. I'm talking about having mandatory English classes so people from every country learn at least the basics of the language. So everyone in the world can at least communicate with each other, even if they're only able to use basic English.
Chinese is difficult for Europeans simply because it shares very few linguistic roots, and the same is generally true for Chinese people learning a European language. The reason it's easier for, say, an English speaker to learn German than Chinese is that European languages will generally have at least a smattering of Latin and Greek in common. It's not because European languages are intrinsically easier.
It's also notable that the dominant language changes significantly over time. English is the current dominant trade language, but before that it was, variously; Dutch, Portuguese, Spanish, Italian (mostly thanks to Venice), Latin, Greek. And that's just in the West!
And for a long time most scientific and intellectual discourse was in French, and the influence of that remains even in the scientific units we use today - SI stands for "Système International", and indeed the adoption of the metric system itself was because of French influence.
English probably won't remain dominant in any field forever, and even in your 25-50 year timeframe I wouldn't be surprised to see significant gains for the East Asian languages, as well as Spanish and Portuguese because of South America.
Lastly, English might be convenient for us native speakers, but I'd imagine that the rest of the world might not agree. How would you like to be told you (or your kids) had to learn Mandarin for the sake of convenience? It seems a bit... colonial to suggest imposing a national language in such a way.
