💔 THE PAINFUL REALITY

Linux search tools are DECADES old and painfully slow

┌─────────────────────────────────────────────────────────────┐
│                    🐌 THE SLOW LEGACY                      │
├─────────────────────────────────────────────────────────────┤
│  grep (1973)  │  2m 14s  │ searching 10GB codebase        │
│  find (1971)  │    45s   │ counting 100k files            │
│  ls   (1971)  │   800ms  │ listing /usr/bin               │
│  du   (1971)  │  1m 30s  │ calculating /home size         │
└─────────────────────────────────────────────────────────────┘

⚠️ Developer Pain Points:

• 🔥 CPU cores sitting idle while single-threaded tools crawl
• 💾 Memory unused while tools read files byte-by-byte
• ⏰ Context switching overhead killing productivity
• 🧠 Cognitive load from waiting for simple operations

"Every second waiting for search results is a second stolen from creativity and innovation"
