This comic is anti-intellectual drivel written by authoritarian Randall Munroe, a former NASA guy who wants people to keep using bad standards instead of creating good ones.
I guess Satoshi shouldn't have created Bitcoin in your eyes, because there were already a bunch of currencies.
Regardless, it's not really relevant here, since Radicle is compatible with git and Cradicle is currently supposed to be compatible with Radicle (only reason that would change is if it turns out adding our improvements breaks Radicle irreparably)
Edit - also just noticed you linked to ngit. That's not really a decentralization-focused project, it's a scam designed to make money, which is why I proposed and helped fund Cradicle instead of contributing to it. The ngit project also started long after Radicle, not before, so if your xkcd strip applied here, it would apply to ngit more than Radicle/Cradicle (unless, like I said before, we find Radicle is unable to handle Cradicle's changes, requiring a new "competing standard" instead)
I understand my reply is not as polite as one should usually be with people providing feedback that was asked for, but the feedback included 0 words and just an xkcd strip I'm extremely tired of seeing, so I stand by this response.
