I don't know who "centimeter" is and never claimed to agree with their viewpoints, so I'm not sure what the other viewpoint is that you're referring to.
The Chinese language looks extremely arcane to me, but that doesn't make it so. Quantum computing is pretty arcane-seeming too. Urbit probably seems arcane to those that know nothing about and haven't invested the time to learn. Fortunately, the docs are very good[1] and updated frequently[2]. They're also publicly available and lots of people[3] are working pretty hard to make them understandable.
Urbit is really welcoming to everyone, should they take a moment to ask about it. Here's[4] where you can find out how to get in and get set up. Here's a place where, earlier today, I offered a free planet to someone that asked[5]. And here's[6] what ended up happening.
