We are able to run our desktops, laptops and servers (and some mobile devices) almost only on free software. Why shouldn't we demand the same for wearables? Is it even possible? If yes, will this happen? What's keeping vendors back in this sense?
This is, of course, not what will happen at first. It will take time for the "race to the bottom" to produce this result.
I'll say this though. I don't consider myself terribly ideological on this point, but in practice I probably am. I am not turning over my hearing and my vision to a company, or indeed any organization. If it's not open, I'll play the luddite. It's not worth it.
If your mission is really to improve the world, giving your users access to raw data and freedom in controlling the device is no-brainer. But that rarely happens, because improving human condition is just a marketing ploy. So instead you get cloud nonsense that isn't really designed to serve you.
Most consumer hardware companies (and that includes especially printer vendors) could do the world a big favour by having courage to admit that whatever companion software they'll write will likely be crap, and leave that to the community.
This is a nice idea but it seems to me that in order for this to work well the hardware and software need to be integrated tightly. Even Google Wear seems to be heading in that direction. I could see Ubuntu trying this but they still seem to be trying to get the phone right so it'll be 2020 before we see anything good with wearables. Maybe Google's modular phone project could lead to open/adaptable hardware for wearables and that opens the door for open/free software too.
Almost all the wearables on the market today are designed to be flaunted.
I disagree with point 2. If you make the wearable into something that it already worn (e.g. watch) and make it just as fashionable you can succeed. The problem is that technology is an industry with almost no fashion sense. The closest product I've seen to succeeding design wise has been the Apple Watch and even it looks a bit clunky (hopefully this will change as the technology improves).
I think we will continue to see successful tech follow that prominent path, but also the hidden one you suggest. Google Glass done right, hearing-enhancements that are barely visible, slim AR/VR goggles that are more like glasses, etc.
We won't see prominent tech/fashion fade away.
But it's getting better every day. I have hope and optimism.
I recently gave a talk about hearing loss, and one of the things I said was that hearing aids make us practically cyborgs. If a hearing aid can help me with my profound hearing loss, imagine what we could do for hearing people -- make your already fantastic hearing even better? Sounds like a win/win to me.
I'm excited about the future -- but I also keep in mind that wearables pose many problems, just like this author pointed out. If we can solve those, we're well on our way to cyborg-hood...
