The context of my claim was about computer information systems becoming centralized. Yes, I understand we do have decentralized washer & dryer machines at home instead of everyone going to centralized laundromat. And building residential houses is still a very local business that resists a hypothetical giant national corporation that builds every house in America. Even Jeff Bezos' Amazon can't conquer 1000 different local building codes and construction techniques to build homes. However, the realm of information technology seems to behave differently.
I like to use the decentralized-Git-to-centralized-Github example because:
- programmers are the ubergeeks that would conceivably be the vanguard of decentralization because they are already predisposed to understand its benefits
- programmers (unlike mass consumers) have the technical know-how to implement their own git server if they wanted to and overcome any challenges of ISP NAT router.
And yet, the vast majority just think: "Hmmm... there's a free service that can host my repo which means I don't have to spend _time_ or _money_ to mess with any of that home setup?!? Sign me up!!!"
There is no "evil capitalist monopoly" that forced Git centralization on to resistant programmers. Instead, the programmers willingly put their code on Github because of the benefits. The economic forces overwhelm the ideals of the decentralized protocol.
As mentioned before, a git distributed protocol can't stop an actor from spending more money on that protocol than others. Github Inc spent extra money on Ruby programmers to create extra features such as issues tracking, web landing page, hosting disk space, reliable backups, DDOS protection, etc. Unequal spending by actors makes one node with better features more desirable than other nodes (such as a personal home node) and this starts a feedback loop of centralization.
To restate the claim earlier: decentralized computer information systems that need to share data is an unstable equilibrium because it depends on having free-will actors not spend extra money on a protocol to gain an advantage which is also an unstable equilibrium.
Even if this thread's article's vision of IPv6 improving direct connectivity were to happen, I still claim the overwhelming majority of programmers would continue to choose something like Github rather than host their repositories on personal home servers. Personally, I wouldn't want my repo to be traced back to my home's ip address. I don't want China DDOS'ing my home ISP connection if they don't like my iPhone app that monitors Hong Kong. If I was a female, I wouldn't want my home git repo to give away my ip address and invite digital stalkers. I'd use Github just for the ability to shield my IPv6 address.
If the programmers -- which we can think of as technical thought leaders -- aren't leading by example (with git) for decentralization, why would we realistically expect other mainstream consumers to adopt decentralized setups? Yes, there will always be decentralized communities but it will always remain niche.
