I would love to see open source hardware take off at that level! You do see plenty of projects at the PCB level, which is nice and likely as far as most people will ever need to go. The price point of a small custom PCB is actually very reasonable now and usually easier to buy than rolling your own anymore. But until you can spin your own silicon with the ease of something like a 3D printer or buy custom low cost/quantity silicon, it doesn't matter what your open source HW design does if you don't have the money or a business to create and distribute it. That's one thing that is very hard to do with something physical and why opensource has worked so well in the software community. There does seem to be some stuff being done here using FPGAs... But they are still a rather expensive way to go just to drop a custom architecture on for now. In the meantime, there is still plenty of software work to do to make a truly useful and professional grade opensouce stack that you can develop on the chips we have.
