This is unironically my plan/playbook with ideas I have for startups. Start with Python, node, or whatever. Then go to Rust once product-market fit has been established.
Rust really hits that sweet spot with memory-management, programming paradigm flexibility, and speed. It’s precisely great for what I need because it’s essentially an ML with good imperative constructs.
If you know exactly what you are building, down to the datatypes, sure, use static typing. But 99% of startups aren't like that. Business development is a highly dynamic process.
Once you hit $1M revenue, rewrite it in Rust or whatever.
