I agree with the sentiment, but your suggestion that USB is losing relevance is a bit of a stretch. Wait, no, not "a bit of a stretch." What's the term I'm looking for? Oh yeah, "Nuts!" :)
Ask anyone on the street to tell you what USB is. If you can find anyone with a three-digit IQ over 12-years-old and under 90 who can't tell you, I'll bake you a cake.
Now, ask them what Thunderbolt is in the context of computers. If you can find even one person in ten in a random sampling who has any idea whatsoever I'd be amazed.
Obviously that's largely due to historical influences and doesn't say anything about whether USB's relevance is increasing or declining, but it does tell you something about the likelihood of it declining anytime soon. Other long-standing standards like PS/2 and RS9 serial didn't have anywhere near the level of consumer awareness and understanding driving them.
With USB3, the bandwidth exceeds all but the most demanding users' needs and so is perfectly acceptable, with the added benefits of being completely invisible to the user who doesn't care, and backwards compatible for the person with legacy components who doesn't want to buy new devices. Contrast that with trying to drive adoption of ANY alternative, even one with much better specs, which requires replacing both computer AND peripherals, and you can see why it will take a major upheaval in the user experience to overcome USB's inertia. Technical superiority isn't enough.
