Replit CEO: AI reverse engineering makes all software de facto open source — what moats remain?
aakashgupta · x · 2026-10-20
Aakash's newsletter expands on his viral REA repo: Replit CEO Amjad Masad tweeted that "what's happening in AI-powered reverse engineering and decompilation is absolutely insane. Pretty soon all software will be de facto open-source" — citing reverse-engineered Adobe products and a GTA V decompile ported to other devices.
The piece asks what moats are left in software:
- Agents can read your app but not your users; server-side toggles and real-user learning loops can't be decompiled.
- Network effects and distribution are company-level bets, but learning from users is something you control weekly.
- Practical playbook: pick an open-source app you know, ask the agent the five questions a competitor would, verify every answer against the code, and log what the agent couldn't tell you — that list is your moat.
