Genuinely I don’t know. I’m studying Physics and Computer Engineering for this purpose. I obviously can’t change the world alone but hopefully others do as able to make a change.
Legislation is #1 but it seems all our politicians are bought and even the good ones get corrupted. Decentralization seems to be the best bet. But hardware is so utterly centralized because of its complexity and of course greed and monopolies.
I don’t even know how it would be possible, but maybe one day we could have something like consumer grade fabricators and electronics made out of materials that are 3d printable. Again, I’m not knowledgeable yet to understand if this is even a remote possibility but… It would be cool.
