Why hasn't this happened already?

I'm willing to believe the hype on LLMs except that I don't see any tiny 1-senior-dev-plus-agents companies disrupting the market. Maybe it just hasn't happened "yet"... But I've been kind of wondering the same thing for most of 2025.

I think it has to get good enough to a point where humans are not the bottleneck for code review and course correction.

I guess the "velocity" multiplier is closer to 10x rather than the 1000x needed for true disruption capability.
