I agree, Jack's in-sentence clarification seems much more possible:

"...the internet will have a single currency."

That seems a tad more reasonable. Alice needs money from Bob, they are in different countries, Alice gets bitcoin and trades it for her countries historically used money. Bitcoin becomes ubiquitous for those types of transactions.

But that's already possible without bitcoin ever getting involved. Not to mention that (I'd wager) 95% of transactions online are single-currency.

I guess I'm just not seeing the benefit to the end user here. Bitcoin is cool and all, but so far it hasn't actually solved anyone's problems (and isn't it incredibly slow to process a transaction these days?)

10 minutes on average to process a transaction, the drive thru line is gonna get a lot longer.
