Given it applies to "A high-end user's connection speed" I am dubious as to the applicability to everyone else - say the bottom 20% of society for example - and so I am most doubtful of the article's "everyone will have 10Gbit" claim.
Maybe "everyone" has a stricter definition than I think.
But as someone who has literally grown up alongside PC's - your link gives confidence to look forward to the crazy ahead. :-)
