As I commented on the Ladybird thread (https://news.ycombinator.com/item?id=48410252), this is an empirical result that sort of tracks the intuition behind "sending a PR that compiles is no longer a sufficient stake to show real commitment."
The article says that whilst the number of edits to individual files has increased by 300% actual releases have only increased by 30%.
I even find this 30% seams higher than what I am seeing.
I love the quote by the Japanese engineer Ohno that a broken machine or system makes a lot of noise. I think it sums up the current situation precisely.
The number Apps with significant usage has gone down slightly.
Is this suggesting less critical thinking?
It's rather the case that AI makes it easier to build and publish an app, but not substantially easier to make a popular app that people will actually use.
