The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

What's love got to do with it? Slack embodied the belief, so common in Silicon Valley, that the best product would win in the end. “Building a product that allows for significant improvements in how people communicate requires a degree of thoughtfulness and craftsmanship that is not common in the development of enterprise software,” the company wrote in its open letter to Microsoft. “How far you go in helping companies truly transform to take advantage of this shift in working is even more important than the individual software features you are duplicating.” And yet, if there’s a lesson of the past four years, it’s that thoughtfulness and craftsmanship only got the company about 10 percent as far as Microsoft did by copy-pasting Slack’s basic design. In its open letter, Slack famously told Microsoft: “You’ve got to do this with love.” In 2020, looking at Slack’s size, the idea seems laughable. What’s love got to do with it?
