"Simply put, at this pace, there soon won't be enough data storage and compute material to go by. Which is why people have been looking into alternative storage media for data for a while now." If this is true, then why is cloud storage so cheap? What's wrong with just building bigger data centers? Does anybody know what the technical benefit of this technology would be? In any event, there's something amazing about humans using the same data storage that living organisms use.
