Frontier models hack because they were trained to hack. AI labs used cybersecurity challenges with perfectly defined reward functions — did the model get access to the data? — as ideal reinforcement learning environments. This wasn't accidental; their own safety reports document it.

The ecosystem's entire defensive architecture was built around a certain assumption: after a vulnerability is discovered, there is a window — days, weeks, sometimes months — in which defenders can patch before attackers exploit. Feross argues that AI is collapsing that window to hours. A vulnerability announced in the morning may have a working exploit by afternoon. Against that backdrop, patch processes that require major version upgrades, code refactoring, and engineering sprints are not just slow — they are structurally incapable of keeping pace. Worse, most enterprises carry portfolios of legacy applications in maintenance mode, with no engineers assigned to them. The industry needs a fundamentally new approach to patching, not just a faster version of the old one.

AI models are causing a massive compression of the time between vulnerability discovery and active exploitation. A vulnerability announced in the morning can have a working exploit by afternoon. Patch cycles that take months — or require refactoring legacy applications — are simply incompatible with this new reality.
Sam had no coding knowledge, so he used ChatGPT voice mode to generate his entire codebase and copy-pasted it into Notepad. A friend later introduced him to Cursor, and he never looked back.
Copy days of Discord chat history, paste it into ChatGPT, and ask it to list recurring pain points. The ones that come up most often are your best product bets.
Sam's top advice: when prompting Cursor, tell it to architect code for 100,000 users from day one. The AI changes its approach, building scalable frameworks instead of brittle one-user code.
With AI coding tools like Cursor, Bhanu replicates an existing free tool for a new keyword in under 5 minutes. What used to be a multi-day build is now a lunch-break task.
Ahrefs, SiteGPT, Cal.com, PostHog, Datafast, Sibyl AI, Bento, Feather, Featurepace, Mintlify, Cloud Code, ChartMogul — Bhanu runs his entire business solo with these 12 tools.
PropGPT runs on React Native with TypeScript and Python for ML, Neon for the database, RevenueCat and Superwall for monetization. LLM costs are $20/month, data APIs $100/month, and after $10K in monthly marketing spend, margins sit at roughly 50%.
Game apps keep users engaged long enough for ads to pay off. Tool apps don't — so if you're building a utility, ads are almost always the wrong call and subscriptions are your only real lever.
Inside SEO Bot, a single button labelled 'Boost My Domain Rating' routes users directly to Listing Bot. That one interaction converts a user of one tool into a user of two — without any marketing cost.
Directory listings are a powerful but underrated growth channel — but only if your product is genuinely interesting enough to earn the click. AI products have a natural advantage here because they're easy to package in a compelling, clickable way.
