Our reading
Facing AI-driven disruption, indie hackers are shifting from building products toward building audience and content as a competitive moat. -

AI-assisted ('vibe') coding has made it so easy to build competing SaaS apps that a plain, unremarkable SaaS product can no longer easily attract signups. -
Our reading

Our reading
Most of the world fails to solve problems because of pride, excessive regulation, and low standards for what counts as a problem worth fixing. -

DHH: Future of Programming, AI, Agentic Engineering, Vibe Coding & Linux | Lex Fridman Podcast #501
- Letting non-programmers vibe-code features into a large existing product destroys its architecture, even when every individual change looks defensible.
- Agent-written pull requests already outclass those of the median human contributor to an open source project.
