I apologize for the digression, but Shopify today reminds me of some Delphi/object pascal shops I’d engaged with earlier in my career. Where the tooling became the primary focus and identity of the staff rather than the solutions (a sort of cargo culting off of that initial business success), and that focus meant the firm ended up being staffed with what could best be described as big fish in little ponds (e.g. the “Delphi expert” who was the guy who stuck with Delphi after everyone else had moved on to other technologies), in a recursive loop.
[1] - other successful companies started with Ruby / RoR (though in many cases it could be called legacy), but right now it seems that 100% of Ruby advocacy comes out of the halls of Shopify. The firm has turned to evangelism.
