Well, would you consider someone who'd only spent a couple of hours of wall time on Unix to be an expert whose opinion was worthy of serious consideration?

Not that I'm flogging Urbit -- or not flogging it, for that matter. I looked at it a while back and decided that I didn't understand it, and wouldn't understand it without spending far more time than I had available. However, that just renders my opinion on the topic useless.

Hmm, that's an interesting point.

I would encourage them [= someone who only spent a couple of hours on Unix] to dig further... broader. Mostly by demonstrating that there are real world problems for which Unix is better suited than competition.

IMO in Urbit -- there was not much more to explore after the few hours. Short of digging even further into the guts of it... and that was very unappealing.

Other people here in the comments mentioned that there's no killer app for Urbit. So my intuition was probably correct [to stop digging].
