The TypeScript team rewrote the entire compiler in native Go. Real-world tests show 8x to 12x faster compilation with lower memory usage. VS Code project compilation dropped from 125.7 seconds to 10.6 seconds. Time to first error in the editor went from 17.5 seconds to under 1.3 seconds.

Armin Ronacher (creator of Flask, Jinja2, CTO of Sentry) argues current programming languages were designed for 'humans who type slowly.' The AI agent era has different needs. He details what agents love/hate, and why Go accidentally became the winner of the agentic coding era.
