The real AI win isn't superhuman agents, it's scaled mediocrity.
Doing less with less at massive scale unlocks tasks that were once uneconomical.
The magic is in aggregate value, not perfect outputs. Empower teams with practical AI tools.

great to see package managers mature (not hat maven/gradle) java dependency overrides are nice - but sometimes just required
