Simon Willison: 'Not So Locked In Any More' — Vendor Lock-In Weakening as AI Slashes Migration Costs
Simon Willison's Blog·medium signal
Simon Willison published a piece arguing that vendor lock-in is weakening, prompted by Mitchell Hashimoto's experience migrating Bun from Zig to Rust and similar conversations at a recent conference. The thesis: AI tools are dramatically reducing the cost of migrating between languages, frameworks, and platforms, which historically was the main enforcement mechanism for lock-in. For builders evaluating technology choices, this suggests bet-hedging and abstraction layers may matter less than they used to.
