1. People *across generations* had to skill up. 2. software being very opaque (very differently from agriculture/mechanized labour) imo is linked to having a plethora of support roles that cannot write software but "handle the human part" and help make it readable, while spreading accountability. Hopefully with a "more readable/more standardized" software development, those [product|project|people] management roles can stop being a drag/bottleneck. (code was never the bottleneck we repeat ourselves since age immemorial)
