This seems like a pretty shallow take. Urbit is (or aspires to be) a platform for server-side use cases; complaining that it's not decentralized is kind of off the mark. But I (more bullish on urbit than 95% of HN, I suspect) agree with this bit:<p>> the deepest problem with Urbit: it’s light on actual substance.<p>At heart, urbit is a platform with no compelling software for it yet, and hence subject to the chicken-and-egg problem that was on the HN front page again today[0]. And urbit is famously hard to develop for, which ought to be enough to spell its doom. But I still check in on it every year or so, because it keeps on plugging away, and what it does have (exactly-once messaging, built-in crypto, and a goofy-but-it-works identity/networking system that allows you to do away with app level authentication) is kind of nifty and it's still not totally clear that it won't go somewhere eventually.<p>0: <a href="https://www.joelonsoftware.com/2000/05/24/strategy-letter-ii-chicken-and-egg-problems/" rel="nofollow">https://www.joelonsoftware.com/2000/05/24/strategy-letter-ii...</a>
