Vibe coders never use MySQL Vibe coders never use MongoDB Vibe coders never use SQLite Vibe coders never use Oracle Vibe coders never use DynamoDB Vibe coders never use Cassandra Every vibe-coded app somehow ends up being: Next.js + Tailwind + Postgres + Claude 😭.

Just see my post comments 😀🤝 nitter.cf/Officially_Dev_/status…

🚨 the AI industry is getting unpredictable. « google builds its most powerful model yet « Anthropic keeps pushing Claude forward « OpenAI continues upgrading GPT « Tibo flirting with Poteto « Lauren flirting with Tibo « xAI refuses to slow down « every company wants the top spot» but here's the real question: who's actually building the model that changes everything? 🤔

Name a programming language better than Python. I'll wait.

🚨 new X update apparently, the number after the letter S in a tweet link can reveal which device was used to post it: ✅ S=19 for Android ✅ S=20 for browser ✅ S=46 for iPhone just something to be aware of when sharing links stay safe..❤️🫂 Turn on notification for useful contents 😎🤝
