"Working remotely is now widespread, and will only become moreso once telepresence robots become ubiquitous."
Telecommuting (much discussed on slashdot over the past decade) is fairly common, but still hardly 'widepread' - only 2.6% of the U.S. employee workforce 'considers the home their primary workplace', and the single largest group of telecommuters are federal employees (3.3%), ahead of private for-profit sector workers (2.6%) (http://globalworkplaceanalytics.com/telecommuting-statistics). And even among those (like myself) who would say my home is my primary workplace (I live about 3 hours drive from my employer) still need to go in to the office once a month or so. Which might work in some parts of Europe, but for most fo the world is unreasonably complicated and expensive. And I suspect the vast vast majority of those of us who telecommute or work remotely are still doing so within national boundaries.
"Translation services, both for written and spoken language are approaching sci-fi-level capabilities."
Bullshit. Well, so far anyway. The linked slashdot story contained a bunch of comments from people saying the skype translation was just about good enough for scheduling another meeting time, but you couldn't use it to do actual work.
"The rise of cryptocurrencies is providing a method for people worldwide to move away from national currencies."
Right up until you need to buy groceries or pay rent.
Of course, all these things will change. Machine translation will definitely get better. Telepresence might get beyond novelty and/or uncanny valley and genuinely make 'going for a beer with the boss' on another continent work. And my landlord might even start accepting bitcoin. But with the possible exception of machine translation, the rest of it will remain the province of fairly well off people for a long time. Well off people like Peter Diamandis.
