In the vaguest-broadest historical sense, guild means a loose hierarchal collective identifing with one category of labour (the craft), who make potentially predictable aspects of the craft less unpredictable through exposition and memorization. Trust pre-requires any "cathedral" such as a "guild" to not abusively attempt to solipsistically shape reality by shaping the perception of reality, such as by investing in predictions disporportionately with certainty in those predictions merely as an expression of desire for those prediction's to be true. Ubuntu roughly translates to "a state caused by social justice called personhood" represents a practice of protecting the differences of others as well as yourself through intentionally detached means, essentially giving attention to whether others are who they want to be and seeking to keep them who they want to be even while fighting them. At scale, that equates to maximizing agency (or choices on who or what to be agent of). Ubuntu fits in the semantics where I placed the keyword 'abusively' or where one might believe in 'solipsism'. A "cathedral" such as a "guild" indubitably makes bets which shape reality solely by shaping the perception of reality, whether one literally believes in solipsism or figuratively believes people build according to what any "cathedral" facilitates their visualization of. Thus, one might claim ubuntu obligates a "cathedral" such as a "guild" to describe reality in a way maximally motivating to the most extremely detached interests.
The following video (licensed creative commons) at one point uses agile as an example, while describing in detail (without explicitly mentioning the word) how give ubuntu to others from the most socially abstract (a leadership) position in the terran civilization (earth):
(if the author had heard about ubuntu, they would probably agree with ubuntu)

Note some grammatical nuances: 1 i say socially abstract rather than leadership, to support the notion of invisible unstructured entirely anonymous influence over a "standalone complex"; socially abstract describes the state of mind and epistemological faculties rather than any particular identity, such as how the (what I'd call) 'temporal identity' of 'the laughing man' is controlled by ideas rather than a person. 2 i say terran civilization to include all intelligent or potentially intelligent species on any terra-class planet, rather than any more limited more common category 3 ubuntu traditionally recognizes animal species as having the potential to achieve more ubuntu than humans on occasion, therefore calling the state humanity contradicts the nature of ubuntu in a fundamental way for no relationship has more potential for detachment than beings physically (not merely cognitively) in capable of communicating the same language.
The following video attempts to describe ubuntu explicitly. The author very prolifically documents popular ideologies commonly referred to as "philosophy" particularly "greek philosophy", which should give them some accreditation to judge the merits of ubuntu. The author currently lives in west africa, which should accredit their ability to accurately research african philosophy.

I would definitely like to get in contact with the author to ask them about licensing all their awesome contributions the internet's commonwealth of information, as creative commons.
To any one interested, I still have interest in updating the rhombus-tech wiki including the tables summarizing the scale and freeness of known major open source projects. I still have interest in PocketCHIP's hardware (though the backing company failed/collapsed), though I believe heavily in urbit's OS architecture so I want to focus my effort in studying urbit with the intention to perhaps one day have hardware such as EOMA (novice) or PocketCHIP (hacker) form a bottom-up libre computer boot to an urbit userland with as minimal middleware as possible. I need to learn/develop-in-mind the standards (or, one might say, the most ubuntu way) first, then make progress in that direction. In short, I want as certain about where I want to go as possible, prior to taking steps in any direction.
Please don't discount me for my absence : P
Side-note: I've joined the U.S. Navy (not a fan of the U.S. military, yet hope to make a difference)
