the real fun of "cyberpunk" is supposed to be open source hardware, modular phones, cyber decks, laptops with six folding displays, ipads with gpio pins and its not a step closer to reality. sad. :( instead we get this web3 nonsense. hate it.
Is it really supposed to be open-source? A common cyberpunk trope is that mega corporate conglomerates own verything. Cyberdecks are modified and reverse-engineered, yes. But generally come from a mega corp.
We have all that, although most of it from smaller Chines manufacturers. More than that we do have truly open source hardware, you can download schematics for almost anything, modify and design your own chips and circuits based on open designs, dream up your own hardware, and if know the right people in Shenzhen you can email it all to them and they'll build it for you.
The reason so few people take advantage of any of this is that it didn't turn out to be that useful.
