My primary worry is that at some point, the hardware will die.
And by crowdfunding I meant crowdfunding of manufacturing; the hardware would be open source, ensuring you could (with enough skills or good enough friends) make your own instead of buying one, and the software ecosystem would be compatible with it.
I guess my inkling is the opposite. It's like video games, even if the hardware dies, you want the software to be able to run, then you can figure out what hardware you can acquire.
A good example of this is the raspberry pi's with all the NES/SNES/etc games. Withing needing to make sure cartridges and old NES's still work, we use a new piece of hardware to give a very similar experience.
Smart watches and other small worn devices will be changing a lot. I'd rather have hw builds posted to something like massdrop as they are iterated, once the software is mostly saved.
