This mostly matches my experience...but I wonder if it ignores significant costs. In particular, how this impact long term maintenance vs. the desire to build new interesting things? (e.g., see https://themaintainers.org/ https://themaintainers.org/). And what about people who just enjoy the act of coding — of wizzing through tickets and gathering points? For another potential cost, take the example given of the Like button in the piece. I'd be curious what Justin Rosenstein now thinks of the example of the Like button. The author says "The business impact of this button is well in the billions: allowing Facebook to (re-) target ads, and "track" users outside of the Facebook site. [...] Everyone is better off for it: the people with the idea and the business." Does everyone here include the users and world? Perhaps if we had better metrics, this SV would work for everything. But in the current world, with profit, data, and growth metrics being incentivized, it may have real societal costs.
