"Something like Globish" or like Basic English, or Kitchen French or Vulgar Latin?
Why would a complete language not suit you as worldwide second language? What is missing is the political will.
However, something like Mandarin Chinese is even more likely. The disadvantage is that you must start learning now, or your grand children will be left behind.
A currency is a tool - it's not a system that people have learned from birth. To switch from one currency to another requires only minor effort, and it's not possible to continue to using the old currency when everyone else switches to the new one.
A language, on the other hand, is something that people would continue using, and you couldn't simple mandate that everyone switch to a different language, they'd simply continue with the old one. Any government that tried to tell people what language to speak would find itself out of power very quickly.
Re: a more serious poll
As silly as switching to the Euro, or more?
