Fist off, I just want to say how awesome this is and how much I hope it succeeds. The type of improvement this would make on society is incredible.

With that being said, what company would actually implement this in their product? It would be amazing for consumers, but terrifying for companies who rely on selling these products. For example, Apple has fought tooth and nail to prevent people from repairing their phones, including swapping the battery. Sure technology advances happen and they get better over time, but if that was a big enough incentive to upgrade, companies wouldn't fight right to repair so hard.

Imagine a company did go out and use it. Would they realistically be able to survive without selling you subscriptions or limiting the lifespan in other ways? History has not shown that business models selling devices once work well.

Honestly curious if anyone else has an idea on how this could work.
