100 years ago data was stored on paper, so 100 years from now who knows what will be possible? As @ben
said, there's a fair chance it'll be "neural" but also "quantum" maybe? But that could be considered legacy by then?
Or we could all be long gone because we burnt all the fossil fuel storing data in blockchains?
As long as everyone understands how blockchains work and where to actually use them we should be fine... But they still haven't.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
