Ideally, how would open source hardware look like for you? I mean that as in after it has achieved something akin to mainstream adoption.
This is a great question. I don't believe it can reach the point of any person simply being able to create their own hardware, unless we're talking about an utopic future with multimaterial 3d printing in small scale, but I can see small businesses being able to manufacture custom open source hardware on demand, based on open standards. For me, the ideal scenario would be something like going into an open hardware service shop and asking for a device with your requirements, and they creating it for you, or repairing/upgrading yours.
Like with skating, many shops can provide you with wheels, decks, gear. Amazon can sell their one-piece e-books at loss, but eventually it can turn to modular open design where nothing is irreplaceable. It's a matter of demand. If there could be a good project and something like a big org or a government programm funding it, it would end well. Like, supplying troubled communities with an e-reader? If only there wouldn't be DRM fuckery, it's golden.
It adds interesting aspects. For example, I work with systems that have 5 I/O modules. Each one keeps a backup of the main controller settings, so that you can replace any component, including the controller.
After a quick question on the next boot, you're up and running again.
Imagine if each module of your ebook reader had enough cheap/slow storage that everything in "main storage" could be replicated across your modules. As long as you only replace a couple of modules at a time, you'd have everything forever.
It doesn't seem super utopic to think a 3d printer could make a pcb, dispense solder paste, pick and place, and heat it to solder it.
Making the ICs themselves on the other hand...
Risc-v to the rescue in the CPU space.
Although I'd say there are big gains if current off the shelf ics are used, even if purists wouldn't call the whole endeavor open source.
Community-owned chip foundries could make it happen.
