I mean, yeah, current implants are shit. They might be shit for the next 100 years. Medicine was shit for a good time, too. So while right now the best implants provide is the novelty factor, I think we'll eventually see them as just another normal thing. See this article, for example, where they might have created a sensor that is actually harmless and dissolves. You just need the right materials. Your reddit post's example with obsolescence is a good one, but we can also overcome that (theoretically), via stuff like nanobots that can dismantle/upgrade implants in a less invasive way, for example. And we might not even need that open wound for a 'jack in the future - Just look at how wireless technology has improved over the last decade. Oh, also that guy with the camera is colourblind. Which is why he has that camera.
